**Methods of A. M. Lyapunov and their Application**

The aim of the current version is to acquaint the reader with

new effects bought within the conception of balance of movement, and also

to summarize convinced researches via the writer during this box of

mathematics. it really is recognized that the matter of balance reduces not

only to an research of platforms of standard differential equations

but additionally to an research of platforms of partial differential

equations. the idea is for this reason constructed during this ebook in such

a demeanour as to make it acceptable to the answer of balance problems

in the case of platforms of normal differential equations as

well as in terms of platforms of partial differential equations.

For the reader's profit, we will now record in brief the contents of

the current monograph.

This ebook contains 5 chapters.

In Sections 1-5 of bankruptcy I we supply the central information

connected with the idea that of metric area, and in addition clarify the

meaning of the phrases that allows you to be used less than. Sections 6 and seven are

preparatory and comprise examples of dynamical platforms in various

spaces. In part eight we outline the concept that of dynamical systems

in metric house, and in addition supply the important theorems from the

book [5] of Nemytsky and Stepanov. In Sections 9-10 we give

the primary definitions, hooked up with the idea that of stability

in the experience of Lyapunov of invariant units of a dynamical system,

and additionally examine the homes of yes good invariant sets.

In part eleven we resolve the matter of a qualitative construction

of a local of a good (asymptotically sturdy) invariant set. In

particular, it's validated that for balance within the feel of Lyapunov

of an invariant set M of a dynamical approach f(p, t) it's necessary,

and on the subject of the presence of a small enough compact local of the set M it's also adequate, that there exist no

motions· f(p, t), P eM, having ex-limit issues in M. The results

obtained listed below are new even to the speculation of standard differential

equations. In Sections 12-13 we supply standards for balance and

instability of invariant units by way of sure functionals.

These functionals are the analogue of the Lyapunov functionality and

therefore the tactic built the following will be regarded as a certain

extension of Lyapunov's moment strategy. the entire result of these

sections are neighborhood in personality. We cite, for instance, one in all these.

In order for an invariant set M to be uniformly asymptotically

stable, it is crucial and enough that during a definite neighborhood

S(M, r) of M there exists a sensible V having the following

properties:

1. Given a host c1 > zero, it really is attainable to discover c2 > zero such

that V(P) > c2 for p(p, M) > c1.

2. V(p) ~ zero as p(p, M) ~ 0.

3. The functionality V(f(p, t)) doesn't elevate for f(p, t) e S(M, r)

and V(f(p, t)) ~ zero as t ~ + oo uniformly relative to p e S(M,

2. For /'2 > zero it really is attainable to discover /'1 and cx1 such that

V(p) cx1 for p(p, M) > /'2·

3. V and (/) ~ zero as p(p, M) ~ 0.

4. dVfdt = fP(1 + V).

5. V(p) ~ -1 as p(p, q) ~ zero, peA, q E A"-. A, and q eM.

Here, as above, p and q are components of tl;te house R, and p(p, M)

is the metric distance from the purpose p to the set M. part 15 features a procedure that makes it attainable to estimate the distance

from the movement to the investigated invariant set. The theorems

obtained during this part will be regarded as supplementations to

Sections 12-14. Sections 1-15 disguise the contents of the 1st chapter,

devoted to an research of invariant units of dynamical systems.

In the second one bankruptcy we provide a built program of the

ideas and techniques of the 1st bankruptcy to the idea of ordinary

differential equations. In part 1 of bankruptcy 2 we strengthen the

theorem of part 14 for desk bound platforms of differential equations,

and it's proven thereby that the Lyapunov functionality V can

be chosen differentiable to a similar order because the correct members

of the approach. within the similar part we supply a illustration of

this functionality as a curvilinear crucial and clear up the matter of

the analytic constitution of the perfect contributors of the method, which

right participants have a zone of asymptotic balance that's prescribed

beforehand. In part 2 of bankruptcy II we give some thought to the

case of holomorphic correct individuals. The functionality V, the existence

of that is confirmed in part 1 of this bankruptcy, is represented

in this example within the kind of convergent sequence, the analytic continuation

of which makes it attainable to acquire the functionality within the entire

region of asymptotic balance. the tactic of development of such

series can be utilized for an approximate answer of sure non-local

problems including the development of bounded strategies in

the kind of sequence, that converge both for t > zero or for t e (- oo,

+ oo). those sequence are bought from the truth that any bounded

solution is defined by means of capabilities which are analytic with respect

to t in a undeniable strip or part strip, containing the true half-axis.

In part three of bankruptcy II we advance the speculation of equations with

homogeneous correct participants. it really is proven specifically that in

order for the 0 resolution of the procedure to be asymptotically

stable, it is crucial and adequate that there exist homogeneous

functions: one optimistic sure W of order m, and one

negative certain V of order (m + 1 - #). such that dVfdt = W,

where # is the index of homogeneity of the fitting contributors of the

system. If the fitting individuals of the procedure are differentiable, then

these capabilities fulfill a procedure of partial differential equations,

the resolution of that are present in closed shape. This circumstance

makes it attainable to offer an important and adequate for asymptotic balance within the case whilst the best members

are varieties of measure p. , without delay at the coeffilients of those forms.

In Sections four and five of bankruptcy II we ponder a number of doubtful

cases: ok 0 roots and 2k natural imaginary roots. We receive here

many effects at the balance, and in addition at the life of integrals

of the procedure and of the relatives of bounded recommendations. In part 6

of bankruptcy II the speculation built in bankruptcy I is utilized to the

theory of non-stationary structures of equations. In it are formulated

theorems that persist with from the result of part 14, and a method

is additionally proposed for the research of periodic solutions.

In part 1 of bankruptcy III we clear up the matter of the analytic

representation of suggestions of partial differential equations in the

case whilst the stipulations of the concept of S. Kovalevskaya are

not chuffed. The theorems bought listed below are utilized in part 2

of bankruptcy III to platforms of standard differential equations. This

supplements the investigations of Briot and Bouquet, H. Poincare,

Picard, Horn, and others, and makes it attainable to boost in

Section three of bankruptcy III a style of creating sequence, describing

a relations of 0-curves for a approach of equations, the expansions of

the correct individuals of which don't include phrases that are linear

in the features sought. the strategy of development of such series

has made it attainable to offer one other method of the answer of the

problem of balance in terms of structures thought of in Sections 3-5

of bankruptcy II and to formulate theorems of balance, according to the

properties of strategies of yes structures of nonlinear algebraic

equations. therefore, the 3rd bankruptcy represents an test at

solving the matter of balance by using Lyapunov's first

method.

In bankruptcy IV we back reflect on metric areas and households of

transformations in them. In part I of bankruptcy IV we introduce

the idea of a common procedure in metric space.

A basic method is a two-parameter relatives of operators from

R into R, having homes just like these present in suggestions of

the Cauchy challenge and the combined challenge for partial differential

equations. therefore, the overall platforms are an summary version of

these difficulties. We additionally increase right here the idea that of balance of

invariant units of normal platforms. In part 2 of bankruptcy IV,

Lyapunov's moment approach is prolonged to incorporate the answer of difficulties of balance of invariant units of basic structures. The

theorems acquired the following yield invaluable and adequate conditions.

They are in line with the tactic of investigating two-parameter

families of operators through one-parameter households of

functionals. We additionally suggest right here a basic technique for estimating

the distance from the movement to the invariant set. In part three of

Chapter IV are given a number of purposes of the built theory

to the Cauchy challenge for platforms of standard differential equations.

Results are acquired the following that aren't present in the identified literature.

The 5th bankruptcy is dedicated to yes purposes of the developed

theory to the research of the matter of balance of the

zero answer of structures of partial differential equations within the case

of the Cauchy challenge or the combined challenge. In part I of

Chapter V are constructed common theorems, which comprise a style of

solving the soundness challenge and that are orientative in character.

In Sections 2-3 of bankruptcy V are given particular platforms of partial

differential equations, for which standards for asymptotic balance are

found. In part three the research of the soundness of a solution

of the Cauchy challenge for linear structures of equations is carried

out by means of a one-parameter kinfolk of quadratic functionals,

defined in W~N>. balance standards normalized to W~NJ are

obtained right here. besides the fact that, the imbedding theorems make it possible

to isolate these circumstances while the soundness should be normalized in C.

In a similar part are given a number of examples of investigation

of balance in terms of the combined problem.

For a winning knowing of the whole fabric discussed

here, it will be important to have an information of arithmetic equivalent

to the scope of 3 college classes. despite the fact that, in a few places

more really expert wisdom is additionally helpful.
