Equilibria, Fixed Points, and Complexity Classes [PDF]
, 2008 Many models from a variety of areas involve the computation of an equilibrium or fixed point of some kind. Examples include Nash equilibria in games; market equilibria; computing optimal strategies and the values of competitive games (stochastic and ...

Croatian Operational Research Review, 2017 A set of sufficient conditions which guarantee the existence of a point x⋆ such that f(x⋆) = x⋆ is called a "fixed point theorem". Many such theorems are named after well-known mathematicians and economists.

Fixed Points Theorems for Non-Transitive Relations [PDF]
Logical Methods in Computer Science, 2022 In this paper, we develop an Isabelle/HOL library of order-theoretic fixed-point theorems. We keep our formalization as general as possible: we reprove several well-known results about complete orders, often with only antisymmetry or attractivity, a mild

Branes and Six Dimensional Fixed Points [PDF]
, 1997 We analyze brane configurations corresponding to non-trivial six dimensional fixed points. Several results previously obtained from a pure field theoretical analysis are rederived in the brane language.Comment: 13 pages, LaTeX2e, using utarticle.cls ...

Fixed points and coupled fixed points in partially ordered ν-generalized metric spaces
Applied General Topology, 2018 New fixed point and coupled fixed point theorems in partially ordered ν-generalized metric spaces are presented. Since the product of two ν-generalized metric spaces is not in general a ν-generalized metric space, a different approach is needed than in ...

Branes, Superpotentials and Superconformal Fixed Points [PDF]
, 1997 We analyze various brane configurations corresponding to field theories in three, four and five dimensions. We find brane configurations which correspond to three dimensional N=2 and four dimensional N=1 supersymmetric QCD theories with quartic ...

Infra-red fixed points in supersymmetry [PDF]
, 2000 Model independent constraints on supersymmetric models emerge when certain couplings are drawn towards their infra-red (quasi) fixed points in the course of their renormalization group evolution.

A counter example on common periodic points of functions
International Journal of Mathematics and Mathematical Sciences, 1998 By a counter example we show that two continuous functions defined on a compact metric space satisfying a certain semi metric need not have a common periodic point.

Existence of Fuzzy Fixed Points and Common Fuzzy Fixed Points for
Mathematics, 2023 This article contains results of the existence of fuzzy fixed points of fuzzy mappings that satisfy certain contraction conditions using the platform of partial b-metric spaces. Some non-trivial examples are provided to authenticate the main results. The

Fixed Points of $p$-Hybrid $L$-Fuzzy Contractions [PDF]
Sahand Communications in Mathematical Analysis, 2021 In this paper, the notion of $p$-hybrid $L$-fuzzy contractions in the framework of $b$-metric space is introduced. Sufficient conditions for existence of common $L$-fuzzy fixed points under such contractions are also investigated.
