In this paper, we prove well-posedness and smoothness results in anisotropic Sobolev spaces for the solutions of boundary value problems with Dirichlet-Robin type boundary conditions for second-order parabolic equations in non-rectangular domains.Mathematics Subject Classification. 35K05, 35K20.
Abstract. In this work we give new results of existence , uniqueness and maximal regularity of a solution to a parabolic equation set in a nonregular domain Q with Cauchy-Dirichlet boundary conditions, wherewith some assumptions on the functions ( ϕ i ) i=1,2 . The right-hand side term of the equation is taken in L 2 (Q) . The method used is based on the approximation of the domain Q by a sequence of subdomains (Q n ) n which can be transformed into regular domains . This work is an extension of the one space variable case studied in [12].Mathematics subject classification (2010): 35K05, 35K20.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
