Lattice paths inside a table, I

Daniel Yaqubi, Mohammad Farrokhi Derakhshandeh Ghouchan, Hamed Ghasemian Zoeram

A lattice path in $Z^{d}$ is a sequence $ν_{1}, ν_{2}, \dots, ν_{k} \in Z^{d}$ such that the steps $ν_{i} - ν_{i - 1}$ lie in a subset $S$ of $Z^{d}$ for all $i=2,\ld…

Contraction of graphs and spanning k-end trees

Hamed Ghasemian Zoeram

A tree with at most k leaves is called k-ended tree, and a tree with exactly k leaves is called k-end tree, where a leaf is a vertex of degree one. Contraction of a graph G along t…

Spanning k-ended trees of 3-regular connected graphs

Hamed Ghasemian Zoeram, Daniel Yaqubi

A tree is called k-ended tree if it has at most k leaves, where a leaf is a vertex of degree one. In this paper we prove that every 3-regular connected graph with n vertices such t…
