Fixed point theorems for hybrid pair of weak compatible mappings in partial metric spaces [PDF]
Mathematica Bohemica, 2023 The notions of compatible mappings play a crucial role in metrical fixed point theory. Partial metric spaces are a generalization of the notion of a metric space in the sense that distance of a point from itself is not necessarily zero. In this paper, we

Random stability and hyperstability of multi-quadratic mappings [PDF]
, 2022 In this paper, we introduce a new quadratic functional equation. In light of this equation, we define the multi-quadratic mappings and reduce the system of n equations defining the multi-quadratic mappings to a single equation.

On Some New Fixed Point Results in Complete Extended b-Metric Spaces
Mathematics, 2019 In this paper, we specified a method that generalizes a number of fixed point results for single and multi-valued mappings in the structure of extended b-metric spaces. Our results extend several existing ones including the results of Aleksic et al.

Coincidence Point Results for Different Types of $ H_b^{+} $-contractions on $m_b$-Metric Spaces [PDF]
Sahand Communications in Mathematical Analysis, 2021 In this paper, we give some properties of $m_b$-metric topology and prove Cantor's intersection theorem in $m_b$-metric spaces. Moreover, we introduce some newclasses of $H_b^+ $-contractions for a pair of multi-valued and single-valued mappings and ...

Multivalued Common Fixed Points Theorem in Complex b-Metric Spaces
Mathematics, 2023 In this paper, we establish a result for the existence of common fixed points for multi-valued mappings, satisfying some contractions for complex-valued b-metric spaces. Finally, we present an example to illustrate and support our results.

Coincidence theorems for nonlinear hybrid contractions
International Journal of Mathematics and Mathematical Sciences, 1997 In this paper, we give some common fixed point theorems for single-valued mappings and multi-valued mappings satisfying a rational inequality. Our theorems generalize some results of B. Fisher, M. L. Diviccaro et al. and V. Popa.

Fixed Point Theorems for Multi-valued α-Fcontractions in Partial metric spaces with Some Application
Results in Nonlinear Analysis, 2021 This paper aims to prove a fixed point theorem for multi-valued mapping using α-F-contraction in partial metric spaces. Furthermore, we prove a fixed point theorem for F-Hardy-Roger's multi-valued mappings in ordered partial metric spaces.

Convexity of Multi-valued Momentum Maps
Geometriae Dedicata, 2005 We extend the famous convexity theorem of Atiyah, Guillemin and Sternberg to the case of non-Hamiltonian actions. We show that the image of a generalized momentum map is a bounded polytope times a vector space. We prove that this picture is stable for small perturbations of the symplectic form.

On Characterizations of Metric Regularity of Multi-valued Maps
, 2018 We provide a new proof along the lines of the recent book of A. Ioffe of a 1990's result of H. Frankowska showing that metric regularity of a multi-valued map can be characterized by regularity of its contingent variation - a notion extending contingent derivative.
