, 2018 Brentano’s theory of continuity is based on his account of boundaries. The core idea of the theory is that boundaries and coincidences thereof belong to the essence of continua.

Approximate Coincidence Point of Two Nonlinear Mappings
Journal of Mathematics, 2013 We study the approximate coincidence point of two nonlinear functions introduced by Geraghty in 1973 and Mizoguchi and Takahashi (ℳ𝒯-function) in 1989.

Coincidences and Fixed Points of Nonself Hybrid Contractions
Journal of Mathematical Analysis and Applications, 2001 Let \((X, d)\) be a complete metrically convex metric space, \(K\) a non-empty closed subset of \(X\), \(F, G: K \to CL(X), S, T\) selfmaps of \(K\). The hybrid contractions in this paper satisfy the inequality \(H(Fx, Gy) \leq \alpha d(Tx, Sy) + \beta[d(Tx, Fx) + d(Sy, Gy)] + \gamma[d(Tx, Gy) + d(Sy, Fx)]\) for each \(x,y \in X\), where \(\alpha ...

On Approximate Coincidence Point Properties and Their Applications to Fixed Point Theory [PDF]
Journal of Applied Mathematics, 2012 We first establish some existence results concerning approximate coincidence point properties and approximate fixed point properties for various types of nonlinear contractive maps in the setting of cone metric spaces and general metric spaces. From these results, we present some new coincidence point and fixed point theorems which generalize Berinde ...

New coincidence and common fixed point theorems
Applied General Topology, 2009 [EN] In this paper, we obtain some extensions and a generalization of a remarkable fixed point theorem of Proinov. Indeed, we obtain some coincidence and fixed point theorems for asymptotically regular non-self and self-maps without requiring continuity and relaxing the completeness of the space. Some useful examples and discussions are also given.

On realizing Nakaoka's coincidence point transfer as an $S$-map [PDF]
Illinois Journal of Mathematics, 1986 Let \(p: E\to B\) be a fiber bundle with compact manifold fiber. The author [J. Differ. Geom. 10, 39-48 (1975; Zbl 0294.55009)] defined a ''transfer'' \(\tau\) : \(H^*(E)\to H^*(B)\) in singular cohomology theory such that \(\tau p^*\) is multiplication by the Euler characteristic of the fiber. \textit{J. C.

A Caseworker Like Me: Does the Similarity between Unemployed and Caseworker Increase Job Placements? [PDF]
This paper examines whether the chances of job placements improve if unemployed persons are counselled by caseworkers who belong to the same social group, defined by gender, age, education, and nationality.

Structural and Cyclical Unemployment: What Can Be Derived from the Matching Function? (in English) [PDF]
We explain movements in the U-V (unemployment and vacancy) space – that is, the relation-ship between stocks of unemployment and job vacancies, known as the Beveridge curve – in the Czech Republic during 1995–2004.

Coincidence and fixed points for hybrid strict contractions
Journal of Mathematical Analysis and Applications, 2004 The author slightly generalizes a condition introduced by \textit{M. Aamri} and \textit{D. El Moutawaki} [ibid. 270, 181--188 (2002; Zbl 1008.54030)] relaxing the commutativity of two mappings to obtain a coincidence theorem for set-valued mappings.
