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.
