Place: Room 614 in the Education & Sciences Building Time: 14:00 We discuss how something remarkably similar to Hall’s marriage theorem appears naturally in context of a conjecture of Grothendieck in algebraic geometry, and how this is useful to prove…

Given a family of sets, a partial choice function chooses an element from some of them. The range of the function is then called a “rainbow set” (the “colors” being the sets). There are two types of conditions that are…

Place: Room 614 in the Education & Sciences Building Time: 14:00 Abstract: A king-non-attacking permutation is a permutation $\pi \in S_n$ such that $|\pi(i)-\pi(i-1)|\neq 1$ for each $i \in \{2,\dots,n\}$. We investigate the structure of the poset of these permutations under…
