已知任意紧致连通可定向三维流形M都有H′-分解,即存在M中一个紧致连通可定向曲面F,F把M切成两个柄体H1和H2,H1∩H2=F,H1∪FH2=M.显见,当M是闭三维流形时,H′-分解与经典Heegaard分解是一致的;当M是带边三维流形时,H′-分解与Heegaard... 已知任意紧致连通可定向三维流形M都有H′-分解,即存在M中一个紧致连通可定向曲面F,F把M切成两个柄体H1和H2,H1∩H2=F,H1∪FH2=M.显见,当M是闭三维流形时,H′-分解与经典Heegaard分解是一致的;当M是带边三维流形时,H′-分解与Heegaard分解是不同的分解.研究了紧致连通可定向带边Seifert流形的H′-分解的结构,主要结果给出这类流形的H′-分解的特征描述. 展开更多

H stability is a new and important concept. In this paper,we discuss the equationx(t)=-a(t)x(t)+∫ t -∞ k(t,s-t,x(s)) d sand we gain a new decision theorem.

In this paper,we discuss the equationx(t)=-a(t)x(t)+∫ t -∞ k(t,s-t,x(s)) d sand we gain a new decision theorem. Using this decision theorem,we obtained a very extensive result of the H uniformly asymptotical stability of this equation. That is,eliminating the restriction that a(t) is bounded. 展开更多

We introduced a new class of fuzzy set-valued variational inclusions with (H,η)-monotone mappings. Using the resolvent operator method in Hilbert spaces, we suggested a new proximal point algorithm for finding approximate solutions, which strongly converge to the exact solution of a fuzzy set-valued variational inclusion with (H,η)-monotone. The results improved and generalized the general quasi-variational inclusions with fuzzy set-valued mappings proposed by Jin and Tian Jin MM, Perturbed proximal point algorithm for general quasi-variational inclusions with fuzzy set-valued mappings, OR Transactions, 2005, 9(3): 31-38, (In Chinese); Tian YX, Generalized nonlinear implicit quasi-variational inclusions with fuzzy mappings, Computers & Mathematics with Applications, 2001, 42: 101-108. 展开更多
