1. 1. Application of Ibragimov's method and Noether's theorem for constructing conservation laws of the linear elasticity model

   University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

   Author : Pouya Sinaian; [2014]
   Keywords : conservation law; Noether s theorem; Ibragimov s method; formal Lagrangian; linear elasticity; the Lame equation.;

   Abstract : In this thesis, conservation laws of the Lame equation describing linear elasticity have been constructed. This has been done by the implementation of two theorems for constructing conservation laws: the new theorem suggested by N H.Ibragimov, and the classical theorem presented by E.Noether. READ MORE
