Kantorovich’s Fixed Point Theorem in Metric Spaces and Coincidence Points

Proceedings of the Steklov Institute of Mathematics, 2019
The authors prove existence and uniqueness of fixed points of a self-mapping on a complete metric space, generalizing and improving the well-known Kantorovich's fixed point theorem in the setting of Banach spaces. Besides of a standard self-mapping, the authors also obtain coincidence point theorems for set-valued mappings on metric spaces.

Zeros of Conic Functions, Fixed Points, and Coincidences

Doklady Mathematics
Concept of conic function with operator coefficients is introduced. Zero existence theorem is proved for such functions. On this basis, fixed point theorem is obtained, for a multivalued self-mapping of a conic metric space, generalizing the recent fixed point theorem by E.S. Zhukovsky and E.A.

CARNIVAL AND HEROIC. POINTS OF COINCIDENCE

2016
Ñвобода, страх, бесстрашие, дискретное время лежат в основании литературоведческих теорий, представляющих полярные явления. Речь идет о концепции карнавализованных жанров М. М. Бахтина и о теории героического искусства, намеченной у М. Мамардашвили. В статье представлены предварительные результаты их сравнения.

On coincidence and hybrid fixed points.

Summary: We prove coincidence and hybrid fixed point results for nonlinear hybrid contractions in symmetric spaces. These results generalize, extend and unify the recent results of \textit{T. L. Hicks} and \textit{B. E. Rhoades} [Nonlinear Anal., Theory Methods Appl. 36, No. 3(A), 331--344 (1999; Zbl 0947.54022)], \textit{T. L. Hicks} [Indian J.
