How to see the forest despite the trees
Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.Abstract One of the major starting points of discrete optimization is the theorem of Nash‐Williams and Tutte on the existence of k$k$ disjoint spanning trees of a graph, along with its counterpart on the existence of k$k$ forests covering all edges of the graph.

Families of quasi-pseudo-metrics generated by probabilistic quasi-pseudo-metric spaces [PDF]
Surveys in Mathematics and its Applications, 2007 This paper contains a study of families of quasi-pseudo-metrics (the concept of a quasi-pseudo-metric was introduced by Wilson, Albert and Kelly) generated by probabilistic quasi-pseudo-metric-spaces which are generalization of probabilistic metric ...

Common Fixed Point Theorem in 2-Menger Space via (S-B) Property [PDF]
, 2019 In this paper, first we prove a common fixed point theorem using weakly compatible mapping in 2- Menger space which generalize the well known results. Secondly, we prove a common fixed point theorem using (S-B) property along with weakly compatible maps.

A Common Fixed Point Theorem for Set-valued Contraction Mappings in Menger Space [PDF]
, 2012 The aim of this paper is to prove a common fixed point theorem for even number of single-valued and two set-valued mappings in complete Menger space using implicit relation. Our result improves and extends the result of Chen and Chang [Common fixed point

ω-cover, k-cover and related spaces on the Pixley-Roy PR[X]
Tạp chí Khoa học Đại học Đồng ThápIn this paper, we study the concepts of ω-cover, k-cover and certain spaces defined by them on the hyperspace PR[X] of finite subsets of a space X endowed with the Pixley-Roy topology. We prove that PR[X] is an ω-Rothberger (resp., ω-Menger, ω-Lindelöf)

On common fixed point theorems for semi-compatible mappings in Menger space [PDF]
, 2010 In this paper, the concept of semi-compatibility and weak compatibility in Menger space has been applied to prove a common fixed point theorem for six self maps. Our result generalizes and extends the result of Pathak and Verma [6]

, 2015 A space X is star-C-Menger if for each sequence (Un : n ∈ N) of open covers of X there exists a sequence (Ksub>n : n ∈ N) of countably compact subsets of X such that {St(Kn; Un) : n ∈ N} is an open cover of X.

Pair (F, h) upper class on some fixed point results in probabilistic Menger space
International Journal of Analysis and Applications, 2020 In this paper, we define the concept of (F, h, α, β, ψ)- contractive mappings in a probabilistic Menger space, which generalizes some previous related concepts. Also, we investigate the existence of fixed points for such mappings. Some examples are given

FIXED POINTS IN INTUITIONISTIC MENGER SPACE
, 2015 The purpose of this paper is to use the new concept of absorbing mappings in intuitionistic Menger space and prove fixed point theorems, without appeal to continuity.
