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. Moreover, when using differential equations Format: Paperback. The papers include topics such as Lie symmetries, equivalence transformations and differential invariants, group theoretical methods in linear equations, namely differential Galois theory and Stokes phenomenon, and the development of some geometrical methods in theoretical physics.

BOOK REVIEW Difference equations by differential equations methods, by Peter E. Hydon, Cambridge, Cambridge University Press,pp., $65 (hardback), ISBN From a historical perspective, difference equations have a longer history than differential equa-tions, dating back to the work of Fibonacci if not earlier.

A non-linear differential equation is a differential equation that is not a linear equation in the unknown function and its derivatives (the linearity or non-linearity in the arguments of the function are not considered here).

There are very few methods of solving nonlinear differential equations exactly; those that are known typically depend on the equation having particular symmetries. A systematic method to derive the nonlocal symmetries for partial differential and differential–difference equations with two independent variables is presented and shown that the Korteweg–de Vries (KdV) and Burger's equations, Volterra and relativistic Toda (RT) lattice equations admit a sequence of nonlocal : R.
