作者 龚黔芬 闻道君 《西南师范大学学报(自然科学版)》 CAS CSCD 北大核心 2012年第2期34-37,共4页
介绍了一类新的包含非扩张映象的Wiener-Hopf方程,建立了非凸变分不等式问题与Wiener-Hopf方程的等价关系,进一步给出了求解非扩张映象不动点和Wiener-Hopf方程的逼近方法,并在一定条件下证明了由该方法所产生的迭代序列的强收敛性.

In this paper,we consider the solvability of generalized variational inequalities involving multi-valued relaxed monotone operators in the framework of Hilbert spaces.Our results mainly improve the corresponding results announced by Verma[R U Verma,Generalized variational inequalities involving multivalued relaxed monotone operators,Appl Math Lett,1997,10:107-109]and many others. 展开更多

In this paper we introduce a new perturbed proximal-projection algorithm for finding the common element of the set of fixed points of non-expansive mappings and the set of solutions of nonlinear mixed variational-like inequalities. The convergence criteria of the iterative sequences generated by the new iterative algorithm is also given. Our approach and results generalize many known results in this field. 展开更多
