报告题目:Uniform Set Systems with Small VC-Dimension

报告摘要:The Vapnik-Chervonenkis (VC) dimension is a central concept in statistical learning theory that has also played a growing role in extremal combinatorics. A classical result in this area, the Sauer-Shelah Lemma, precisely determines the maximum size of non-uniform set systems with bounded VC-dimension. In contrast, the uniform setting, where each set has the same size, remains far less understood, and determining tight bounds in this case is a longstanding open problem.

In this talk, I will discuss recent progress on this question.
