Abstract

In this paper, we first give a sharp sufficient condition on degree sum for a connected graph to have a spanning tree whose maximum of degree sum of two adjacent vertices are bounded. These improve some previous results on the spanning tree with bounded maximum degree. Next, we also use our main result to study the generalized rainbow connection of graphs. In particular, we give some degree sum conditions for a connected graphs to have a bounded (1,2)- rainbow connection number.

Connected Dominating Sets in Triangulations

A dominating set of a graph $G$ is \emph{connected} if it induces a connected graph in $G$. For planar triangulations, it has been known since 1990 that every $n$-vertex triangulation with $n\ge4$ admits a connected dominating set of size at most $n/2 - 1$, and no improvement to this bound was known for over three decades. We break this longstanding barrier by showing that every $n$-vertex triangulation has a connected dominating set of size at most $10n/21$. Equivalently, every triangulation admits a spanning tree with at least $11n/21$ leaves. This result has graph drawing applications, establishing a bound for one-bend free sets and improving the known bound for simultaneous planar embeddings. The connected dominating set results extend readily to show that an $n$-vertex triangulation of a surface of Euler genus $g$ has a connected dominating set of size at most $10n/21+O(\sqrt{gn})$.

Curves on the torus with few intersections

Aougab and Gaster [Math. Proc. Cambridge Philos. Soc. 174 (2023), 569-584] proved that any set of simple closed curves on the torus, where any two are non-homotopic and intersect at most k times, has a maximum size of $k+O(\sqrt{k}\log k)$. We determine the maximum size of such a set for every k. In particular, the maximum never exceeds k+6, and it does not exceed k+4 when k is large. As this quantity coincides with the maximal number of columns of a generic k-modular matrix with two rows, our result also settles the column number problem, a problem of interest in combinatorial optimization, for such matrices.

Spectral extrema on closed surfaces of fixed Euler genus

We investigate a classical extremal problem in combinatorics and topological graph theory: determining the maximum spectral radius $spex(n,γ)$ of all $n$-vertex graphs embeddable on a closed surface of Euler genus $γ$. Building on seminal contributions by Boots and Royle, Cao and Vince, and Hong in the 1990s; Ellingham and Zha in 2000; Dvořák and Mohar in 2010; Tait and Tobin in 2017; and Liu, Ning, and Wang in 2026, we provide a complete characterization of spectral extremal graphs for any fixed Euler genus $γ$ and all sufficiently large $n$. The extremal graph attaining $\operatorname{spex}(n,γ)$ is unique, necessarily edge-extremal, and, roughly speaking, is constructed from the join $K_2 \nabla P_{n-2}$ by adding exactly $3γ$ edges. As a consequence, we derive asymptotically tight estimates for $\operatorname{spex}(n,γ)$, strengthening a classical bound due to Ellingham and Zha [J. Combin. Theory B, 2000]. We further characterize the extremal structures for the projective plane and torus, sharpening earlier bounds of Hong [J. Combin. Theory B, 1995]. For the planar case, we establish an explicit vertex threshold of $4.5\times 10^6$ for the Tait--Tobin theorem. Our approach combines extremal constructions of cellular embeddings, topological edge-switching techniques, and walk-counting estimates for large-scale substructures, revealing a bridge between spectral extremality and surface topology.
