Spanning trees in random regular uniform hypergraphs
, 2022 Let Gn,r,s denote a uniformly random r-regular s-uniform hypergraph on the vertex set {1, 2,... , n}. We establish a threshold result for the existence of a spanning tree in Gn,r,s, restricting to n satisfying the necessary divisibility conditions ...

Low chromatic spanning sub(di)graphs with prescribed degree or connectivity properties [PDF]
, 2022 International audienceGeneralizing well-known results of Erd ̋os and Lov ́asz, we show that every graph G contains a spanning k-partite subgraph H with λ(H) ≥ ⌈ k−1k λ(G)⌉, where λ(G) is the edge-connectivity of G.

Simplicial and Conical Decomposition of Positively Spanning Sets
, 2020 We investigate the decomposition of a set $X$, which positively spans the Euclidean space $\mathbb{R}^{d}$ into a set of minimal positive bases, we call simplices, and into maximal sets positively spanning pointed cones, i.e. cones with exactly one apex.

-connected chordal graphs with minimum number of spanning trees
, 2023 Let $k$ be the largest integer such that \( m \ge \tfrac{(n-k)(n-k-1)}{2}+qk \ge q(n-1) \) for some positive integers $n, m, q$. Let $S(q,n,m)$ be a set of all $q$-connected chordal graphs on $n$ vertices and $m$ edges for \( \tfrac{n-k}{2} \ge q \ge 2 \)
