报告内容简介：

The distribution of cycle lengths in graphs of given basic parameters, such an minimum degree, connectivity, edge number, etc, has been extensively studied in the literature and remains one of the most active and fundamental research areas in graph theory. In this talk, I will introduce some problems together with our recent progress on cycle lengths in graphs of given minimum degree and degree sum between two non-adjacent vertices.
