โœฆ Synopsis

By means of a new technique based on a class of functions ฮ  (t, s, r ), new oscillation criteria are established for certain neutral partial functional differential equations. The main results are of a high degree of generality and sharper than many previous results.

An existence result and a priori bound for the solution of a second-order nonlinear parabolic equation are established. Also a generalized tanh-function method is used for constructing exact travelling wave solutions for the nonlinear diffusion equation of Fisher type originated from the considered
