The dynamics of quasiperiodically driven interval translation mappings is presented and re-searched. Such mappings, on the one hand, generate simple and general enough discrete-time dynamical systems and, on another, detect ...

This paper presented a comparison principle for matrix differential equations. We employ the unified Liapunov’s direct method via matrix-valued Liapunov functions and some differential inequalities.

We study the instantaneous support shrinking phenomenon for a doubly nonlinear degenerate parabolic equation with inhomogeneous absorption in the case of slow diffusion, when the initial Cauchy data are, in general, Radon ...
