"Five or six things Ehsaan wants me to talk about"

Ehsaan gave me a list of five or six things he wants me to talk about this Friday. The list includes: the definition of ringed spaces, locally ringed spaces, schemes; an example of a non-affine scheme, etc. I plan to talk about these things.

David Pitts, University of Nebraska

"Cartan Pairs and Extensions of Inverse Semigroups”

Jacob Tsimmerman, University of Toronto

“Bounding Torsion in Geometric Families of Abelian Varieties”

"Torsion-free groups: linear independence and computable categoricity"

Ross Willard, Pure Mathematics, University of Waterloo

"Adding Gaussian elimination to local consistency checking - 2"

In this second of several lectures, I will present a polynomial-time consistency checking algorithm for constraint networks over a finite template having a Taylor polymorphism. I conjecture that the algorithm is complete for Maltsev templates, and in future lectures will provide evidence supporting this conjecture.

“Varieties versus schemes”

Last week, we saw the definition of a scheme. In this weeks talk, well present more examples of schemes and illustrate how, in some cases, schemes provide a better framework than varieties for studying certain geometric questions.
