Abstract:
A system of heat equations in a nonholonomic frame is considered. Solutions of the system are constructed in the form of general sigma functions of Abelian tori. As a corollary, we solve the problem (of general interest) to describe the generators of the ring of differential operators annihilating the sigma functions of families of plane algebraic curves.
Keywords:nonholonomic frame, heat equations, sigma and theta functions in several variables, discriminant varieties.
