| Soohyun Park (Hebrew University of Jerusalem) |
| Euler characteristic-like invariants and positivity patterns in geometric contexts predicted by combinatorics |
| Algebra seminar |
| Time: 3:05PM |
| Location: 232 |
We will discuss intrinsic structures and positivity properties of certain Euler characteristic-like invariants which appear in a wide range of contexts in algebraic combinatorics. Note that the positi... More |

| Glueing invariants of Donaldson--Thomas type |
| Algebra seminar |
| Time: 8:30AM |
| Location: Zoom |
Donaldson--Thomas invariants are numerical invariants associated to Calabi--Yau varieties. They can be obtained by glueing singularity invariants from local models of a suitable moduli space. B... More |

| Solving linear recurrence relations in terms of solutions of lower order recurrences |
| Algebra seminar |
| Time: 3:05PM |
| Location: 232 |
We use difference Galois theory to classify recurrence relations of orders 3 and 4 that are solvable in terms of solutions of recurrence relations of order 2. We also develop algorithm... More |

| The zeros of the Riemann zeta function and its generalization to modular forms |
| Algebra seminar |
| Time: 3:05 |
| Location: 232 |
According to the Riemann hypothesis, the Riemann zeta function should have zeros only at negative even integers and complex numbers with real part 1/2. We will study the completed Riemann zeta f... More |

| Rok Gregoric (John Hopkins University) |
| Even periodization |
| Algebra seminar |
| Time: 3:05PM |
| Location: 232 |
In this talk, I will present work in progress on even periodization. This is an operation on spectral stacks, which roughly approximates them as closely as possible with affines corresponding to even ... More |
