On the Absence and Non-Uniqueness of Classical Solutions of Mixed Problems for the Telegraph Equation with a Nonlinear Potential

Abstract

For the telegraph equation with a nonlinear potential given in the first quadrant, we consider the first and the second mixed problem, for which we study issues related to the absence and non-uniqueness of classical solutions.
