"Divisibility of Discriminants of Homogeneous Polynomials"

We prove several square-divisibility results about the discriminant of homogeneous polynomials of arbitrary degree and number of variables, when certain coefficients vanish, and give characterizations for when the discriminant is divisible by p2 for p prime.

"Back-and-forth relations of Abelian groups"

We will provide a partial characterization of the back-and-forth relations on countable reduced Abelian p-groups. This will, in turn, help us to provide upper bounds on the Scott complexities of such structures. This work relies heavily on Ulm's theorem, and so a proof sketch will be given.

"Model theory of differential fields in positive characteristic"

Talk #1 (1:00 - 2:15 pm)

Jing Xuan Chen, Department of Pure Mathematics, University of Waterloo

"Holomorphic bisectional curvature (continued)"

Christine Eagles, Department of Pure Mathematics, University of Waterloo

"Canonical Basis Property"

We will be reading "Rings of finite Morley rank without the CBP" by Loesch and Palacin. This talk will continue a construction of a ring of finite Morley rank without the CBP.

Sean Monahan, Department of Pure Mathematics, University of Waterloo

"Normal schemes and what-not"

We’ll discuss what makes a scheme “normal”, and in the event that your scheme is weird we’ll see how to “normalize” it. I plan to discuss other related concepts; maybe regularity and local factoriality.

Valentina Harizanov, George Washington University

"Cohesive Powers of Computable Structures"

Luke MacLean, Department of Pure Mathematics, University of Waterloo

Notions of Complexity Within Computable Structure Theory

"This talk will broadly cover three notions of measuring complexity within computable structure theory"

Nolan Pyott, Department of Pure Mathematics, University of Waterloo

"Generalized GCDs as Applications of Vojta’s Conjecture"

Talk #1 (1:00pm–2:30pm)
