Regularity and existence of solutions to parabolic equations with nonstandard p(x,t),q(x,t)-growth conditions
Abstract. We study the Cauchy-Dirichlet problem for a class of nonlinear parabolic equations driven by nonstandard \(p(x,t),q(x,t)\)-growth condition. We prove theorems of existence and uniqueness of weak solutions in suitable Orlicz-Sobolev spaces, derive global and local in time \(L^{\infty}\) bounds for the weak solutions.
Keywords: existence theory, nonlinear parabolic problems, nonstandard growth, regularity theory.
