| Jeremy Usatine (FSU) |
| Crepant resolutions via stacks |
| Algebra seminar |
| Time: 3:05 |
| Location: LOV 301 |
Consider an invariant that behaves nicely for smooth varieties, such as Euler number, Betti numbers, or Hodge numbers. Suppose we want a version of this invariant for singular varieties that sees inte... More |

| Rational torsion and reducibility for abelian varieties associated to newforms |
| Algebra seminar |
| Time: 3:05PM |
| Location: LOV 301 |
Let f be a newform and A its associated abelian variety. We have shown before that for certain primes r, if A is an optimal semistable elliptic curve with reducible torsion subgroup A[r], then A has r... More |

| Benson Farb (University of Chicago) |
| 3-dimensional hypersurfaces and intermediate Jacobians |
| Algebra seminar |
| Time: 3:05 |
| Location: Zoom |
Clemens-Griffiths discovered in 1971 a surprising connection between two questions (all terms will be defined in the talk) 1. When is a 3-dimensional hypersurface rational (i.e. ... More |

| Soumya Sankar (Utrecht University) |
| Relations between Frobenius eigenvalues of abelian varieties over finite fields |
| Algebra seminar |
| Time: 3:05 |
| Location: Zoom |
Elliptic curves over a finite field F_q come in two flavours: ordinary and supersingular. As q varies over powers of a fixed prime p, the eigenvalues of Frobenius of an ordinary elliptic curve are uni... More |

| Akash Sengupta (University of Waterloo) |
| Uniform bounds on Sylvester-Gallai type configurations of polynomials |
| Algebra seminar |
| Time: 3:05 PM |
| Location: Zoom |
The classical Sylvester-Gallai theorem says that if a finite set of points in the Euclidean plane has the property that the line joining any two points contains a third point from the set, then all th... More |

| Pedro Souza (Goethe-Universität, Frankfurt) |
| On the topology of the moduli space of tropical Z/pZ-covers |
| Algebra seminar |
| Time: 3:05PM |
| Location: Zoom |
We study the topology of the moduli space of (unramified) Z/pZ-covers of tropical curves of genus g≥2 where p is a prime number. By recent work of Chan-Galatius-Payne, the (reduced) homology ... More |

| Matteo Costantini (Universität Duisburg-Essen) |
| Spaces of flat surfaces |
| Algebra seminar |
| Time: |
| No location for this even specified. |
A non-zero holomorphic one form on a Riemann surface endows it with a flat metric with conical singularities. Such an object is called flat surface. While spaces of flat surfaces with fixed typ... More |

| Hung-Chun Yu (FSU) |
| An Introduction to Algebraic K-Theory |
| Candidacy Exam |
| Time: 1pm |

| Priyankur Chaudhuri (University of Milan) |
| Algebraically integrable foliations and canonical bundle formula |
| Algebra seminar |
| Time: 3:05PM |
| Location: Zoom |
Situations in which the canonical divisor of a smooth projective variety is the pullback of a divisor on a lower dimensional variety, are quite commonplace in higher dimensional algebraic geometry. In... More |

| Sam Ballas (FSU) |
| Classical and Exotic Dehn Filling |
| Geometry and Topology |
| Time: 3:05 |
| Location: 301 |
Dehn filling is a topological operation where one starts with a 3-manifold, M, with torus boundary and builds a closed manifold by gluing a solid torus to it along their respective boundaries. There a... More |

| Ishan Banerjee (Ohio State University) |
| Monodromy and vanishing cycles for curves in an algebraic surface |
| Algebra Seminar |
| Time: 3:05 |
| Location: LOV 301 |
This talk will be about the monodromy group associated to a family of algebraic curves in an algebraic surface as a subgroup of the mapping class group. I will start by surveying some older results in... More |

| Brandon Doherty (FSU) |
| Comparison of cubical sets with and without symmetries |
| Geometry and Topology Seminar |
| Time: 3:05 |
| Location: 301 |
We discuss an adjoint triple of functors which defines a comparison between categories of cubical sets on which model structures for (infinity,1)-categories have been established, and cubical sets hav... More |

| Homology of spaces of curves on blowups |
| Algebra seminar |
| Time: 3:05PM |
| Location: 301 |
Let C be a smooth projective curve and X be a smooth projective variety. We will consider the space of degree d algebraic maps from C to X. When X is a projective space, Segal discovered an inter... More |

| Supersolvable posets and fiber-type arrangements |
| Algebra seminar |
| Time: 3:05PM |
| Location: 301 |
We present a combinatorial analysis of fiber bundles of generalized configuration spaces on connected abelian Lie groups. These bundles are akin to those of Fadell--Neuwirth for configuration spaces, ... More |
