Towards a conjecture of Birmelé-Bondy-Reed on the Erdős-Pósa property of long cycles
Jie Ma, Chunlei Zu
A conjecture of Birmelé, Bondy and Reed states that for any integer , every graph without two vertex-disjoint cycles of length at least contains a set of at…
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…
Bipartite-ness under smooth conditions
Tao Jiang, Sean Longbrake, Jie Ma
Given a family of bipartite graphs, the {\it Zarankiewicz number} is the maximum number of edges in an by bipartite graph that does n…
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…
Extremal problems of Erdős, Faudree, Schelp and Simonovits on paths and cycles
Binlong Li, Jie Ma, Bo Ning
For positive integers , let denote the least integer such that every -vertex graph with at least vertices of degree at least contains a path on…
Improvements on induced subgraphs of given sizes
Jialin He, Jie Ma, Lilu Zhao
Given integers and , let consist of all integers such that every -vertex graph with edges contains an -vertex induced subgraph with edges, and l…
