Reductions and Exact Solutions of Nonlinear Wave-Type PDEs with Proportional and More Complex Delays
Publikováno v:
Mathematics, Vol 11, Iss 3, p 516 (2023)
The study gives a brief overview of publications on exact solutions for functional PDEs with delays of various types and on methods for constructing such solutions. For the first time, second-order wave-type PDEs with a nonlinear source term containi

We study nonlinear pantograph-type reaction–diffusion PDEs, which, in addition to the unknown u=u(x,t), also contain the same functions with dilated or contracted arguments of the form w=u(px,t), w=u(x,qt), and w=u(px,qt), where p and q are the fre

The paper deals with nonlinear reaction–diffusion systems of two PDEs of a rather general form, which contain arbitrary functions and several delays. Reductions of such non-stationary nonlinear reaction–diffusion systems to simpler systems of sta

We present a new method for constructing exact solutions of nonlinear delay PDEs using special solutions of simpler auxiliary PDEs without delay. The application of the method is demonstrated on nonlinear reaction–diffusion and wave-type equations
