In mathematics, a differential equation is an equation that relates one or more functions and their derivatives. Such relations are common; therefore, differential equations play a prominent role in many disciplines including engineering , physics , economics , and biology. Mainly the study of differential equations consists of the study of their solutions the set of functions that satisfy each equation , and of the properties of their solutions. Only the simplest differential equations are solvable by explicit formulas; however, many properties of solutions of a given differential equation may be determined without computing them exactly. Often when a closed-form expression for the solutions is not available, solutions may be approximated numerically using computers.

Metrics details. A number of nontrivial conservation laws of some difference equations, viz. Symmetries and the more recent ideas and notions of characteristics multipliers for difference equations are also discussed. The role of symmetries of difference equations is now well established and the applications of the symmetries in the analysis especially reduction of the equations are also well documented see [ 1 — 4 ]. However, the role and construction of conservation laws for partial difference equations PDEs , to the best of our knowledge, is somewhat new but the preliminary concepts and definitions are available even in the context of variational equations see [ 5 — 7 ]. These conservation laws, as in the case of differential equations, have a variety of applications especially as another tool in the reduction of the equation under scrutiny. The aim of this work is to obtain the conservation laws of PDEs which are of interest, viz.

It seems that you're in Germany. We have a dedicated site for Germany. This book shows how Lie group and integrability techniques, originally developed for differential equations, have been adapted to the case of difference equations. Difference equations are playing an increasingly important role in the natural sciences. Indeed, many phenomena are inherently discrete and thus naturally described by difference equations. More fundamentally, in subatomic physics, space-time may actually be discrete. Differential equations would then just be approximations of more basic discrete ones.

- Поддержи. Коммандер глубоко вздохнул и подошел к раздвижной стеклянной двери. Кнопка на полу привела ее в движение, и дверь, издав шипящий звук, отъехала в сторону. Чатрукьян ввалился в комнату.

Конечно. - Бринкерхофф рассеянно кивнул, стараясь не смотреть на лиф ее платья. - Когда знаменатель равняется нулю, - объясняла Мидж, - результат уходит в бесконечность. Компьютеры терпеть не могут бесконечности, поэтому выдают девятки.
