Oscillation properties for solutions of a kind of partial fractional differential equations with damping term

The aim of the present paper is to obtain sufficient conditions for oscillation of solutions of partial fractional differential equations with the damping term of the form D1+α+,t u(x;t)+p(t)D^α+,t u(x;t)=a(t)Δu(x;t)+Σm i=1 ai(t)Δu(x;t−τi)−q(x;t)∫t0 (t−ξ)^−α u(x;ξ)dξ;(x;t)∈Ω×R+≡G. Two examples are given to illustrate the main results.
