Mark van Hoeij (Florida State University)
How to define the natural numbers
Algebra and Its Applications
Time: 3:35pm
Location: This will be an online seminar
Lets construct the natural numbers:

N = {0, 1, 2, 3, 4, ...}

The dots mean "and so on”.  But what does “and so on” mean? It means this:

* I gave some examples.* Constructin... More

Grayson Jorgenson (Florida State University)
Secant indices of projective varieties
Algebra and Its Applications
Time: 3:35pm
Location: fsu.zoom.us/j/248086872
To each subvariety of projective space we associate an integer sequence that records the maximal cardinalities of its intersections with linear subvarieties. We call this the sequence of secant indice... More

Benjamin Prather (Florida State University)
Quasialgebra structure of the octonions
Algebra and Its Applications
Time: 3:35pm
Location: LOV 104
I plan to discuss topics from the 1998 paper "Quasialgebra structure of the octonions" by H. Albuquerque, S. Majid.

Tyler Foster (Florida State University)
Witt vectors and factorization statistics
Algebra and Its Applications
Time: 3:35pm
Location: LOV 104
 
Feb 24
Rizwanur Khan (The University of Mississippi)
Non-vanishing of Dirichlet L-functions
Algebra and Its Applications
Time: 3:35 PM
Location: LOV 201
L-functions are fundamental objects in number theory. At the central point s = 1/2, an L-function L(s) is expected to vanish only if there is some deep arithmetic reason for it to do so (such as in th... More

Amod Agashe (Florida State University)
The modular number, congruence number, and multiplicity one
Algebra and Its Applications
Time: 3:35pm
Location: LOV 104
The modular number and congruence number are certain invariants associated to modular abelian varieties (e.g., elliptic curves), and in joint work with K. Ribet, we proved a relation between them. Mul... More

Dave Massey (Northeastern)
Lê Cycles, Jacobian Blow-Ups, and Segre Classes
Algebra and Its Applications
Time: 3:35pm
Location: LOV 104
Having defined the Lê cycles in the previous talk, I will explain how they are related to the exceptional divisor of the blow-up of the jacobian ideal. This will enable us to see that the sum of the ... More

Dave Massey (Northeastern)
Lê Cycles and the local topology of Complex Hypersurfaces
Algebra and Its Applications
Time: 3:35pm
Location: LOV 104
I will recall the definition of the Milnor fibration of a complex hypersurface, define the Lê cycles and Lê numbers of a hypersurface with arbitrary singularities, and give several examples. Then I ... More

Paolo Aluffi (Florida State University)
Generalities on proper intersections and blow-ups
Algebra and Its Applications
Time: 3:35pm
Location: LOV 104
Prof. David Massey will visit the department for two weeks, and give talks in our seminar. My talk will review several notions from algebraic geometry which will be assumed as background in Massey’s... More
