The initial-boundary value problems for parabolic equations in domains with conical points. (English) Zbl 1328.35072

Summary: We consider a initial-boundary value problem for parabolic equation in a domain with conical points. We establish the weak well-posedness of the problem and the regularity of the solution. We also receive asymptotic formulas for the solution near the conical points.
