Symmetries and Applications of Differential Equations : In Memory of Nail H. Ibragimov (1939-2018)

This book is about Lie group analysis of differential equations for physical and engineering problems. The topics include: \-- Approximate symmetry in nonlinear physical problems \-- Complex methods for Lie symmetry analysis \-- Lie group classification, Symmetry analysis, and conservation laws \-- Conservative difference schemes \-- Hamiltonian structure and conservation laws of three-dimensional linear elasticity \-- Involutive systems of partial differential equations This collection of works is written in memory of Professor Nail H. Ibragimov (1939-2018). It could be used as a reference book in differential equations in mathematics, mechanical, and electrical engineering.
