Abstract | 本文中在较弱的条件下对向量值Musielak-Orlicz 空间的一些已有的理论结果进行了改进, 并给出了在此类一致凸空间上的Radon-Riesz 定理的一个有用的变体; 研究了由Musielak-Orlicz 函数生成的凸模的性质, 用Musielak-Orlicz 函数的一致凸性给出了由它生成的凸模的次微分映射是(S)+型映射的一个充分条件; 在此理论基础上, 证明了很广的一类具变分结构的拟线性椭圆算子是(S)+型的; 引入了具有变指数p(x)型的Musielak-Orlicz 函数及p(x)-Laplacian 型算子的新概念, 它包含通常的p(x)-Laplacian 算子为其特殊情形, 证明了p(x)-Laplacian 型算子是(S)+型的;获得了一批关于p(x)-Laplacian 型方程解的存在性与多解性的结果. 本文中所提出的p(x)-Laplacian 型算子的概念及获得的相关结果是对由De N´apoli 和Mariani 提出的p-Laplacian 型算子及相应结果的本质性的改进和发展. |
Other Abstract | In this paper, under some weaker conditions we have improved some theories of the vector valued Musielak-Orlicz spaces and give some useful variants of Radon-Riesz theorem
in the uniformly convex spaces. We studies the property of the convex modular which is generated by a Musielak-Orlicz function, using the uniform convexity of the Musielak-
Orlicz function, we give a sufficient condition for the (S)+-property of the subdifferential mapping of the convex modular generated by it; And based on this we obtain the (S)+-property of a wide class of the quasilinear elliptic operators with the variational structure.We introduce the new notion of a special subclass of the Musielak-Orlicz function, which is called of type with variable exponent, and the p(x)-Laplacian type operators which include
the p(x)-Laplacian operator as a special case. We have showed the (S)+-property of the p(x)-Laplacian type operators. As an application of this result, we obtain the existence and multiplicity of solutions for the class of equations of the p(x)-Laplacian type. The notion of p(x)-Laplacian type operators and the results obtained in this paper are the essence of the improvement and development of p-Laplacian type operators and the corresponding results in [10] by De N´apoli and Mariani . |
