Convexity and the Euclidean Metric of Space-Time [PDF]

open access: yesUniverse, 2017
We address the reasons why the “Wick-rotated”, positive-definite, space-time metric obeys the Pythagorean theorem. An answer is proposed based on the convexity and smoothness properties of the functional spaces purporting to provide the kinematic framework of approaches to quantum gravity.

Length of a curve is quasi-convex along a Teichmuller geodesic

open access: yes, 2010
We show that for every simple closed curve \alpha, the extremal length and the hyperbolic length of \alpha are quasi-convex functions along any Teichmuller geodesic.

On ω-Interpolative Berinde Weak Contraction in Quasi-Partial b-Metric Space

open access: yesInternational Journal of Analysis and Applications, 2021
The aim of this paper is to introduce interpolative weak contraction in the notion of Berinde weak operator in quasi-partial b-metric space and to extend and generalize fixed point results by adopting the condition of ω-admissibility.

BERGMANN AND HARDY SPACES AND CONJUGATE OF THEM

open access: yesВестник Донского государственного технического университета, 2018
It is proved that  space is strongly notmed, and  is neither strongly notmed, nor uniformly convex. A standard form of the linear functionals over  space and over metric spaces of  0 < p £ 1, is determined.

Enriched rational type contractions in quasi-Banach spaces and generalized convex b-metric spaces

open access: yesApplied General Topology
In this paper, we define enriched rational type contraction in the setting of quasi-Banach spaces and prove the existence and uniqueness of fixed point of the enriched contraction by using Krasnselskii iteration procedure.
