Place: Room 614 in the Education & Sciences Building Time: 14:00 Abstract: Open Gromov-Witten (OGW) invariants should count pseudoholomorphic maps from Riemann surfaces with boundary to a symplectic manifold, with boundary conditions and various constraints on boundary and interior marked…

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…

Place: Room 614 in the Education & Sciences Building Time: 14:00 Abstract: Hyperbolic manifolds play an important role in geometry and topology, and in the 1980s Gromov introduced a notion of large-scale negative curvature that is strong enough to…
