Inverse problems for a mixed parabolic-hyperbolic equation with a degenerate parabolic part

摘要

In this paper, inverse problems are posed and studied todetermine the factors of the right-hand sides of a mixed parabolic-hyperbolictype with a degenerate parabolic part, depending on time. On thebasis of the theory of integral equations, the corresponding uniquenesstheorems and the existence of solutions of inverse problems were proved,and explicit formulas for the solution were obtained.
