Spanning k-ended trees of 3-regular connected graphs
Electronic Journal of Graph Theory and Applications, 2017 A vertex of degree one is called an end-vertex and the set of end-vertices of G is denoted by End(G). For a positive integer k, a tree T be called k-ended tree if $|End(T)| \leq k$. In this paper, we obtain sufficient conditions for spanning k-trees of 3-

Gale diagrams of convex polytopes and positive spanning sets of vectors
Discrete Applied Mathematics, 1984 A positive k-spanning set (PkSS) in Euclidean m-space \({\mathbb{R}}^ m\) is a set of points such that each open half-space of \({\mathbb{R}}^ m\) bounded by a hyperplane through the origin contains at least k points of the set. In this paper, the author investigates the maximal cardinality of a minimal (with respect to inclusion) PkSS of \({\mathbb{R}}

The complexity of finding low chromatic spanning sub(di)graphs with prescribed connectivity properties [PDF]
, 2023 As usual λ(G) denotes the edge-connectivity of the graph G. It was shown in [2] that every graph G contains a spanning (λ(G)+1)-partite subgraph H such that λ(H)=λ(G) and one can find such a spanning subgraph in polynomial time.

Flipping Plane Spanning Paths [PDF]
, 2022 Let S be a planar point set in general position, and let P(S) be the set of all plane (straight-line) spanning paths for S. A flip in a path P ∈ P(S) is the operation of removing an edge e ∈ P and replacing it with a new edge f on S such that the ...

Graphs where each spanning tree has a perfect matching
, 2021 An edge subset $S$ of a connected graph $G$ is called an anti-Kekul\\u27{e} set if $G-S$ is connected and has no perfect matching. We can see that a connected graph $G$ has no anti-Kekul\\u27{e} set if and only if each spanning tree of $G$ has a perfect ...

Hippocampal Asymmetry Increases with Age
Anatomia, 2023 It is unclear whether differences between the two brain hemispheres become larger or smaller with increasing age. Given that the hippocampus is particularly susceptible to age-related changes, here, we set out to investigate the correlation between ...
