报告摘要:
While Tur\'{a}n type problem is the most studied topic in extremal combinatorics, some of the most basic bipartite degenerate Tur\'{a}n problems remain elusive. In this talk, I will discuss some recent advancements on this topic and new results on bipartite graphs arising from geometric shapes and periodic tilings commonly found in nature, including even prisms, planar hexagonal tiling and quadrangulations of plane, cylinder and torus. This is joint work with Jun Gao, Oliver Janzer, and Zixiang Xu.
