Conservation laws for nonlinear telegraph equations
A complete conservation law classification is given for nonlinear telegraph (NLT) systems with respect to multipliers that are functions of independent and dependent variables. It turns out that a very large class of NLT systems admits four nontrivial local conservation laws. The results of this work are summarized in tables which display all multipliers, fluxes and densities for the correspond...
متن کاملEnhanced Group Analysis and Conservation Laws of Variable Coefficient Reaction–Diffusion Equations with Power Nonlinearities
A class of variable coefficient (1+1)-dimensional nonlinear reaction–diffusion equations of the general form f(x)ut = (g(x)u nux)x + h(x)u m is investigated. Different kinds of equivalence groups are constructed including ones with transformations which are nonlocal with respect to arbitrary elements. For the class under consideration the complete group classification is performed with respect ...

متن کاملAnalysis of Linear Variable Coefficient Delay Differential-algebraic Equations
The analysis of general linear variable coefficient delay differential-algebraic systems (DDAEs) is presented. The solvability for DDAEs is investigated and a reformulation procedure to regularize a given DDAE is developed. Based on this regularization procedure existence and uniqueness of solutions and consistency of initial functions is analyzed as well as other structural properties of DDAEs...
