A Linear Inverse Problem for a Multidimensional Mixed-Type Second-Order Equation of the First-Kind

摘要

In this paper, we study the well-posedness of a linear inverse problem for a mixed-type second-order multidimensional equation of the first kind. We prove the unique solvability of this problem in a certain function class with the help of “ ε -regularization”, a priori estimates, and successive approximation methods.
