Abstract:We prove the unique existence of a classical solution for a linear parabolic system of nondivergence and nondiagonal form. The key ingredient is to combine the energy estimates with Schauder estimates and to obtain a uniform boundedness of a solution.
Keywords: linear parabolic system, nondivergence, nondiagonal form, $L^{\infty }$-estimate, \newline Schauder estimate
