Conditions for Forced Oscillation of a Class of Parabolic Equations with Deviating Arguments

In order to establish conditions for forced oscillations with continuous deviating arguments, a special kind of nonlinear parabolic equation with a specific boundary value condition is investigated here in this paper. And two different types of oscillatory criteria are found. One concerns with the property of a typical sort of differential inequality and the with a specical kind of limitations of the infimum and the supremum of an integral, both of whitch are under the same prerequisite. The results generalize and improve some of the existing results about forced oscillation.
