Some existence theorems of maximal elements for the family of GB-majorized mappings are proved under noncompact setting of product FCspaces. Some applications to fixed point and system of minimax inequalities are given in product FC-spaces. These theorems improve, unify and generalize many important results in recent literature.展开更多

Multilinear function series and transforms in free probability theory. Adv.

According to the linear representation of linked partitions, Chen et al.(Chen W Y C, Wu S Y J, Yan C H. Linked partitions and linked cycles. European J. Combin., 2008, 29(6): 1408–1426) de?ned the concept of singly covered minimal elements. Let L(n, k) denote the set of linked partitions of [n] with k singly covered minimal elements and let P(n, k) denote the set of permutations of [n] with k cycles. In this paper, we mainly establish two bijections between L(n, k) and P(n, k). The two bijections from a different perspective show the one-to-one correspondence between the singly covered minimal elements in L(n, k) and the cycles in P(n, k).展开更多

A new existence theorem of maximal elements of a family of set-valued mappings involving condensing mappings is proved in locally FC-uniform spaces. As applications, some new equilibrium existence theorems of generalized game involving condensing mappings are established in locally FC-uniform spaces. These results improve and generalize some known results in literature to locally FC-uniform spaces. Some further applications of our results to the systems of generalized vector quasi-equilibrium problems will be given in a follow-up paper.展开更多

By further analyzing the formation and development of minimalist garden, factors of minimalist garden were concluded as the following 6 aspects:application of traditional elements, innovative introduction of natural environment elements, unique application of traditional design elements, application of concise geometric features, application of new garden elements, demonstration of the four-dimensional element-time. 5 characteristics of minimalist garden were proposed as:A. Concise geometric figures; B. innovative application of classical nature;C. Application of rich materials; D.Overlaid application of a series of elements; E. Expressing landscape environment objectively. Research on minimalism will help to understand garden types of different characteristics and provide practical references for modern garden design.展开更多
