In this paper, we consider the transmission problem for the heat equation on a bounded plane sector in $L^{p}$-Sobolev spaces. By Applying the theory of the sums of operators of Da Prato-Grisvard and Dore-Venni, we prove that the solution can be splited into a regular part in $L^{p}$-Sobolev space and an explicit singular part.
Keywords: transmission heat equation, sums of linear operators, singular behavior, non-smooth domains.
