In this paper, a general idea of Presic type $L$-fuzzy fixed point results using some weakly contractive conditions in the setting of metric space is initiated. Stability of $L$-fuzzy mappings and associated new concepts are proposed herein to complement their corresponding notions related to crisp multi-valued and single-valued mappings. Illustrative nontrivial examples are provided to support the assertions of our main results. 相似文献

SOME FURTHER GENERALIZATIONS OF KY FAN’S MINIMAX INEQUALITY AND ITS APPLICATIONS TO VARIATIONAL INEQUALITIES 总被引:1,自引:0,他引:1
The purpose of this paper is to introduce the concept of generalized KKM mapping andto obtain some general version of the famous KKM theorem and Ky Fan’s minimaxinequality.As applications,we utilize the results presented in this paper to study the saddlepoint problem and the existence problem of solutions for a class of quasi-variationalinequalities.The results obtained in this paper extend and improve some recent results of[1-6]. 相似文献

This paper presents a new method for global analysis of nonlinear system. By means of transforming the nonlinear dynamic problems
into point mapping forms which are single-valued and continuous, the state space can be regularly divided into a certain number
of finitely small triangle elements on which the non-linear mapping can be approximately substituted by the linear mapping
given by definition. Hence, the large range distributed problem of the mapping fixed points will be simplified as a process
for solving a set of linear equations. Still further, the exact position of the fixed points can be found by the iterative
technique. It is convenient to judge the stability of fixed points and the shrinkage zone in the state space by using the
deformation matrix of linear mapping. In this paper, the attractive kernel for the stationary fixed points is defined, which
makes great advantage for describing the attractive domains of the fixed points. The new method is more convenient and effective
than the cell mapping methodl[1]. And an example for two-dimensional mapping is given. 相似文献

The global structure of the mapping T_n:x→[x~2]_n,is studied.The symmetricunconnected substructures of T_2 is coincident with[1]by computer,but for n=3 thesymmetry of these substructures vanishes.As n is increasing,the global bifurcationstructure of T_n is shown.Finally,similar results for the mapping T_n,μ:x→[μx~2 ]_n are alsoproved. 相似文献

In this paper,based on ref[1],the axisymmetrical buckling of simply supportedcylindrical sandwich shells under the action of uniform axial load is solved by a rigorousmethod.The classical theory of shells is used for the two face sheets and the core isconsidered as a three-dimensional elastic body.A series of transcendental equations areobtained,from which the critical loads can be calculated by numerical methods.Numericalexamples are given to compare with the solutions of sandwich shell theories. 相似文献

In this paper,we study the interior layer phenomena of singular perturbation boundaryvalue problems for semilinear systems:εy” = f(t,y.ε)(a0 is a small parameter,y.f. A and B are n-dimensional vector functions.Thisvector boundary value peoblem does not appear to have been studied,although the scalarboundary problem has been treated extensively.Under appopriate assumptions we obtainexistence of solution as in the scalar problem and the estimate of this solution in terms ofappropriate inequalities as well. 相似文献
