Abstract
The paper considers an initial-boundary value problem for a semilinear parabolic equation on a simple connected directed graph. A weak solution to the problem is defined in the appropriate functional spaces and conditions for continuity and transmission at the graph vertices are provided. The unique solvability of the problem is proved.
