Spectral and pseudospectral functions of various dimensions for symmetric systems
Vadim Mogilevskii
The main object of the paper is a symmetric system $J y'-B(t)y=ł\D(t) y$ defined on an interval $\cI=[a,b) $ with the regular endpoint . Let $\f(\cd,ł)$ be a matrix solution of…

Group classification of nonlinear wave equations
V. I. Lagno, R. Z. Zhdanov, O. Magda
We perform complete group classification of the general class of quasi linear wave equations in two variables. This class may be seen as a broad generalization of the nonlinear d'A…

Symmetry and Exact Solutions of the Maxwell and SU(2) Yang-Mills Equations
R. Z. Zhdanov, V. I. Lagno
We give the overview of solution techniques for the general conformally-invariant linear and nonlinear wave equations centered around the idea of dimensional reductions by their sy…
