具有结构阻尼和外阻尼的非自治非线性梁方程的拉回Dδ,E1-吸引子
Pullback Dδ,E1-Attractor for the Nonautonomous Nonlinear Beam Equations with Structural Damping and External Damping
【摘要】 考虑了具有结构阻尼和外阻尼的非自治非线性粘弹性梁方程的拉回Dδ,E1-吸引子.首先利用Galerkin方法,证明了在齐次边界条件和初始条件下系统在V×H和D(A)×V中的整体解的存在唯一性;其次通过先验估计,证明了系统的拉回吸收集的存在性;最后证明了系统满足拉回Dδ,E1-条件(C),从而证明了系统的强拉回Dδ,E1-吸引子的存在性.
【Abstract】 In this paper,we consider the pullback Dδ,E1 attractor for the nonautonomous nonlinear elastic equation of beam with structural damping and external damping.By Galerkin method,the existence and uniqueness of global solutions are proved under homogeneous boundary conditions and initial conditions in V×HandD(A)×V;By prior estimates,the existence of the pullback absorbing set is obtained;By proving the pullback Dδ,E1-condition(C), the existence of the strong pullback Dδ,E1-attractor of beam equation is also given.
