Abstract:
Ramsey type problems were introduced in 1930. This subject has been a hot topic in mathematics for decades now due to their intrinsic beauty, wide applicability, and overwhelming difficulty. Ramsey theory on posets was initiated by Nešetřil and Rödl in 1984. In this talk, we introduce the concept and some progress of Ramsey numbers, Gallai-Ramsey numbers, Ramsey multiplicity for posets (including Boolean lattices and ordered graphs).

 

The lecture can be followed by zoom if necessary:
