Periodic and Fixed Points for Caristi-Type G-Contractions in Extended b-Gauge Spaces

Journal of Function Spaces, 2021
In this paper, we introduce extended b-gauge spaces and the extended family of generalized extended pseudo-b-distances. Moreover, we define the sequential completeness and construct the Caristi-type G-contractions in the framework of extended b-gauge ...

Fast Sequential Clustering in Riemannian Manifolds for Dynamic and Time-Series-Annotated Multilayer Networks

IEEE Open Journal of Signal Processing, 2021
This work exploits Riemannian manifolds to build a sequential-clustering framework able to address a wide variety of clustering tasks in dynamic multilayer (brain) networks via the information extracted from their nodal time-series.

ℐ𝒦-SEQUENTIAL AND ℐ𝒦-FRÉCHET-URYSOHN SPACES

Проблемы анализа
Notions of ℐ^𝒦-Fréchet-Urysohn and ℐ^𝒦-sequential spaces are studied by letting ideals ℐ, 𝒦 of subsets of natural numbers to play measurable role in the well-established concepts of Fréchet Urysohn and sequential spaces. Relation among those spaces in

Matrix transformations and convex spaces

International Journal of Mathematics and Mathematical Sciences, 1988
In a Hausdorff topological linear space we examine relations between r-convexity and a condition on matrix transformations between null sequences. In particular, for metrizable spaces the condition implies r-convexity.

Constraints on sequential discontinuities from the geometry of on-shell spaces

Journal of High Energy Physics, 2023
We present several classes of constraints on the discontinuities of Feynman integrals that go beyond the Steinmann relations. These constraints follow from a geometric formulation of the Landau equations that was advocated by Pham, in which the ...

Tanaka spaces and products of sequential spaces [PDF]

, 2007
summary:We consider properties of Tanaka spaces (introduced in Mynard F., {\it More on strongly sequential spaces\/}, Comment. Math. Univ. Carolin. {\bf 43} (2002), 525--530), strongly sequential spaces, and weakly sequential spaces. Applications include

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
