“…For n = 1, i.e., for one convolution equation, there are numerous publications devoted to this solvability problem; a complete solution was presented in [3,4] for the case of convex domains in the complex space of arbitrary dimension. For smooth domains, full solution of a system of nonhomogeneous convolution equations was proposed in the paper [5], where there is also a list of the most important references on the topic. We dwell on the results of [5] in more detail.…”
