Nonuniqueness of the solution of the problem of determining the coefficients of the leading terms of equations in partial derivatives
The author shows that it is not possible to construct examples of uniqueness of solutions of hyperbolic and parabolic differential equations. The analysis is based on a general class of differential equation and then the author proves it for a particular case. The analysis is good as a class work exercise.
