, 2012 We prove practical formulas for the Reidemeister coincidence number, the Lefschetz coincidence number and the Nielsen coincidence number of continuous maps between oriented infra-nilmanifolds of equal dimension.

PPF dependent common fixed point theorems for mappings in Banach spaces
, 2013 We prove the existence of the PPF dependent common fixed point theorems and the PPF dependent coincidence points for a pair of mappings satisfying some contractive conditions in Banach spaces where the domains and ranges of the mappings are not the same.

On fixed point theorems for mappings with PPF dependence
Journal of Inequalities and Applications, 2014 In this paper, we consider two families Ψ1 and Ψ2 of mappings defined on [0,+∞) satisfy some certain properties. Using the mentioned properties for Ψ1 and Ψ2, we prove the analogous PPF dependent fixed point theorems for mappings as in Drici et al ...

Bounds for fixed points and fixed subgroups on surfaces and graphs
, 2011 We consider selfmaps of hyperbolic surfaces and graphs, and give some bounds involving the rank and the index of fixed point classes. One consequence is a rank bound for fixed subgroups of surface group endomorphisms, similar to the Bestvina‐Handel bound

Fixed point results for the α-Meir-Keeler contraction on partial Hausdorff metric spaces
, 2013 The purpose of this paper is to study fixed point theorems for a multi-valued mapping satisfying the α-Meir-Keeler contraction with respect to the partial Hausdorff metric ℋ in complete partial metric spaces.

Some fixed point theorems in locally p-convex spaces
, 2013 In this paper we investigate the existence of a fixed point of multivalued mapson almost p-convex and p-convex subsets of topological vectorspaces. Our results extend and generalize some fixed point theorems on the topicin the literature, such as the ...

Some new fixed point theorems for set-valued contractions in complete metric spaces
, 2011 In this article, we obtain some new fixed point theorems for set-valued contractions in complete metric spaces. Our results generalize or improve many recent fixed point theorems in the literature.MSC: 47H10, 54C60, 54H25, 55M20.

A fixed point theorem for smooth extension maps
Fixed Point Theory and Applications, 2014 Let X be a compact smooth n-manifold, with or without boundary, and let A be an (n−1)-dimensional smooth submanifold of the interior of X. Let ϕ:A→A be a smooth map and f:(X,A)→(X,A) be a smooth map whose restriction to A is ϕ.

, 2013 The aim of this paper is to obtain coupled fixed point theorems for self-mappings defined on an ordered closed and convex subset of a quasi-Banach space. Our method of proof is different and constructive in nature.

Nonstabilized Nielsen coincidence invariants and Hopf-Ganea homomorphisms [PDF]
, 2006 In classical fixed point and coincidence theory the notion of Nielsen numbers has proved to be extremely fruitful. We extend it to pairs .f1;f2/ of maps between manifolds of arbitrary dimensions, using nonstabilized normal bordism theory as our main tool.
