Oscillation of the solutions of parabolic differential equations of neutral type. (English) Zbl 0673.35037

The authors develop sufficient conditions for the oscillation of the solution of a linear parabolic equation of neutral type in a domain with piecewise smooth boundary. Six theorems are presented and two numerical examples are illustrated.
