Abstract

We consider the first initial–boundary value problem for a second-order Petrovskii parabolic homogeneous system with constant coefficients in a bounded domain \(\Omega \) on the plane with curvilinear lateral boundaries nonsmooth at \(t=0 \). The existence of a solution of this problem in the class \( C^{2,1}_{x,t}(\overline {\Omega })\) is proved by the method of boundary integral equations.
