Strong chromatic index of bipartite graphs

Yanli Hao, Tianchi Yang, Xingxing Yu

An edge-coloring of a graph is called a strong edge-coloring if all its color classes are induced matchings in ; the minimum number of colors required for such a coloring, d…

A hypergraph bipartite Turán problem with odd uniformity

Jie Ma, Tianchi Yang

In this paper, we investigate the hypergraph Turán number . Here, denotes the -uniform hypergraph with vertex set $\left(\cup_{i\in [t]}X_i\…

Minimum Topology Attacks for Graph Neural Networks

Mengmei Zhang, Xiao Wang, Chuan Shi +3

With the great popularity of Graph Neural Networks (GNNs), their robustness to adversarial topology attacks has received significant attention. Although many attack methods have be…

On the maximum number of edges in k-critical graphs

Cong Luo, Jie Ma, Tianchi Yang

A graph is called -critical if its chromatic number is but any proper subgraph has chromatic number less than . An old and important problem in graph theory asks to deter…

On extremal numbers of the triangle plus the four-cycle

Jie Ma, Tianchi Yang

For a family of graphs, let denote the maximum number of edges in an -vertex graph which contains none of the members of as a sub…

Upper bounds on the extremal number of the 4-cycle

Jie Ma, Tianchi Yang

We obtain some new upper bounds on the maximum number of edges in -vertex graphs without containing cycles of length four. This leads to an asymptotically optimal bound o…

Non-repeated cycle lengths and Sidon sequences

Jie Ma, Tianchi Yang

We prove a conjecture of Boros, Caro, Füredi and Yuster on the maximum number of edges in a 2-connected graph without repeated cycle lengths, which is a restricted version of a lon…

Some exact results on -cycles: stability and supersaturation

Jialin He, Jie Ma, Tianchi Yang

Extremal problems on the -cycle played a heuristic important role in the development of extremal graph theory. A fundamental theorem of Füredi states that the Turán number…

Counting critical subgraphs in -critical graphs

Jie Ma, Tianchi Yang

Gallai asked in 1984 if any -critical graph on vertices contains at least distinct -critical subgraphs. The answer is trivial for . Improving a result of…

Decomposing -free graphs under degree constraints

Jie Ma, Tianchi Yang

A celebrated theorem of Stiebitz asserts that any graph with minimum degree at least can be partitioned into two parts which induce two subgraphs with minimum degree at lea…
