Weak infinitesimal generator for a stochastic partial differential equation with time delay.
Weak periodic solutions of some quasilinear parabolic equations with data measures.
Weak periodic solutions of the boundary value problem for nonlinear heat equation
The paper deals with the existence of periodic solutions of the boundary value problem for nonlinear heat equation, where various types of nonlinearities are considered. The proofs are based on the investigation of Liapunov-Schmidt bifurcation system via Leray-Schauder degree theory.
