摘要
讨论了中立型抛物偏微分方程tu(x,t)-p(t)u(x,t-τ)[]+ni=1ai(t)u(x,t-γj(t))=mj=1qj(t)Δu(x,t-σj(t)),(x,t)∈Ω×R+解的振动性.
This paper discusses the oscillations of solutions for neutral parabolic partial differential equations of the formtu(x,t)-p(t)u(x,t-τ)+ni=1a i(t)u(x,t-γ i(t)) =mj=1q j(t)Δu(x,t-σ j(t)),(x,t)∈Ω×R +Sufficient conditions are established for oscillations of solutions of the equations.
