Preliminary design analysis for the solar optical telescope main mirror actuator [PDF]
The resolution of the SOT Gregorian telescope was maintained if the conic foci of the elliptical secondary and parabolic primary were made to coincide within plus or minus 38 microns across the prime focus plane and to within 5 microns in focus. An error

Generalized Contractive Mappings and Weakly α-Admissible Pairs in G-Metric Spaces
The Scientific World Journal, 2014 The aim of this paper is to present some coincidence and common fixed point results for generalized (ψ, φ)-contractive mappings using partially weakly G-α-admissibility in the setup of G-metric space.

Note on strict contractive conditions and common fixed point theorems with application
Demonstratio Mathematica, 2017 In this note we point out errors in the proofs of first two theorems contained in Demonstratio Mathematica, Vol. XLVI, no 2, 2013, 405-413. We also rectify the erratic theorems by employing a proper setting.

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 ...

Existence of coupled coincidence best proximity point [PDF]
Surveys in Mathematics and its ApplicationsThis work of optimality is engaged with couple coincidence best proximity point. We have developed some optimal results where control functions and non-linear weak inequalities are evident. Further using our results, we establish some fixed point results.

Multivalued generalizations of fixed point results in fuzzy metric spaces
Nonlinear Analysis, 2016 This paper attempts to prove fixed and coincidence point results in fuzzy metric space using multivalued mappings. Altering distance function and multivalued strong {bn}-fuzzy contraction are used in order to do that.

Coincidence and fixed point theorems for functions in S-KKM class on generalized convex spaces
Fixed Point Theory and Applications, 2006 We establish a coincidence theorem in S-KKM class by means of the basic defining property for multifunctions in S-KKM. Based on this coincidence theorem, we deduce some useful corollaries and investigate the fixed point problem on uniform spaces.
