Affine Connection Representation of Gauge Fields
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 There are two ways to unify gravitational field and gauge field. One is to represent gravitational field as principal bundle connection, and the other is to represent gauge field as affine connection. Poincaré gauge theory and metric‐affine gauge theory adopt the first approach. This paper adopts the second.

Advances in Mathematical Physics, Volume 2021, Issue 1, 2021., 2021 In this article, Box‐Cox and Yeo‐Johnson transformation models are applied to two time series datasets of monthly temperature averages to improve the forecast ability. An application algorithm was proposed to transform the positive original responses using the first model and the stationary responses using the second model to improve the nonparametric ...

Theoretical Economics, Volume 16, Issue 1, Page 129-160, January 2021., 2021 Predictions about the future are commonly evaluated through statistical tests. As shown by recent literature, many known tests are subject to adverse selection problems and cannot discriminate between forecasters who are competent and forecasters who are uninformed but predict strategically.

Cauchy Sequences in Semimetric Spaces [PDF]
Proceedings of the American Mathematical Society, 1972 As the main result we prove that every semimetrizable space has a semimetric for which every convergent sequence has a Cauchy subsequence. This result is used to show that a T 1 {T_1} space X is semimetrizable if and only if it is a pseudo-open π \pi -image of a metric space.

The local triangle axiom in topology and domain theory
Applied General Topology, 2013 We introduce a general notion of distance in weakly separated topological spaces. Our approach differs from existing ones since we do not assume the reflexivity axiom in general.

Mathematics, 2018 The T1-spaces induced by the fuzzy semi-metric spaces endowed with the special kind of triangle inequality are investigated in this paper. The limits in fuzzy semi-metric spaces are also studied to demonstrate the consistency of limit concepts in the ...

Convergence in Fuzzy Semi-Metric Spaces
Mathematics, 2018 The convergence using the fuzzy semi-metric and dual fuzzy semi-metric is studied in this paper. The infimum type of dual fuzzy semi-metric and the supremum type of dual fuzzy semi-metric are proposed in this paper. Based on these two types of dual fuzzy

Advances in Mathematical Physics, Volume 2020, Issue 1, 2020., 2020 In this paper, we present a common fixed point result for a pair of mappings defined on a b‐metric space, which satisfies quasi‐contractive inequality with nonlinear comparison functions. An application in solving a class of integral equations will support our results.

Common Fixed Point Results for a Pair of Multivalued Mappings in Complex‐Valued b‐Metric Spaces
Abstract and Applied Analysis, Volume 2020, Issue 1, 2020., 2020 Several fixed point results for the existence of common fixed points of multivalued contractive mappings have been established in complex‐valued metric space. In this paper, we study the existence of common fixed points for a pair of multivalued contractive mappings satisfying some rational inequalities in the framework of complex‐valued b‐metric ...
