摘要:Abstract(#br)Let Π be a finite lattice of integer points in a box of R n and f an increasing mapping in terms of the componentwise ordering from Π to itself. The well-known Tarski's fixed point theorem asserts that f has a fixed point in Π. A simple expansion of f from Π to...

摘要:Abstract(#br)The problem of minimizing the sum of nonsmooth, convex objective functions defined on a real Hilbert space over the intersection of fixed point sets of nonexpansive mappings, onto which the projections cannot be efficiently computed, is considered. The use of pro...

摘要:... In the last years, some papers have appeared trying to extend the most important results about existence of fixed points for nonexpansive mappings to this wider class of mappings (see, for instance, [2,5,9,10,15]). In this paper we continue this project proving that Banach s...

摘要:Abstract(#br)In this paper, we have developed some common fixed point theorems satisfying generalized F-contraction for multivalued maps in Dynamic programming in the context of b-metric-like spaces. We have also discussed an example to validate our results. Finally, we have evin...

摘要:Abstract(#br)In the present paper we prove some new fixed point theorems for self-mappings defined on a complete metric space with a w -distance. These results extend some previous fixed point theorems in this field to more general contractive conditions in the setting of w -d...

摘要:Abstract(#br)In this note we give one more solution to the open question of the existence of contractive definitions which are strong enough to generate a fixed point but which do not force the mapping to be continuous at the fixed point (R. Kannan, 1969 [9]; B.E. Rhoades, 1988 [...

摘要:Abstract(#br)In this paper, we define the class of ( α , β ) -nonexpansive mappings which is properly larger than the class of α -nonexpansive mappings and prove that every ( α , β ) -nonexpansive mapping T : C → C has an approximate fixed point sequence, where C is a n...

摘要:Abstract(#br)We are interested in fixed points in Boolean networks, i.e. functions f from { 0 , 1 } n to itself. We define the subnetworks of f as the restrictions of f to the subcubes of { 0 , 1 } n , and we characterize a class F of Boolean networks satisfying the following...

摘要:Abstract(#br)In this manuscript, we initiated to study a notion of graphical rectangular metric space and established some fixed point theorems in the aforesaid space. We also discuss the structure of an open ball and Hausdorffness of the new metric. Suitable examples and graphs ...

摘要:... Each such function has a unique fixed point. We study p -adic dynamical systems generated by the (2, 2)-rational functions. We show that the fixed point is indifferent and therefore the convergence of the trajectories is not the typical case for the dynamical systems. Sie...
