Oscillatory and periodic solutions to a diffusion equation of neutral type

We examine a PDE with piecewise constant time delay. The equation is of neutral type since it contains the derivative ut at different values of the t-argument. Furthermore, the argument deviation changes its sign within intervals of unit length, so that the given PDE is alternately of retarded and a...
