"How using OER made me a better teacher"
I began working with open educational resources (OER) not long after my arrival at the University of Lethbridge. There were two immediate appeals: affordability (I could provide a textbook to students at no cost) and adaptability (I could edit the source to get the textbook I wanted). When the only commercial textbook we could find for a new course was over $300, I knew it was time to consider OER.

"Introduction to Elementary Sieve"
This talk aims at introducing sieve theory in an elementary way. Sieve problem and two elementary sieves - larger sieve and square sieve - will be discussed in detail, as well as their applications and a broad overview of the historical development of sieve theory. Some standard results including the Mobius inversion formula will also be covered in this talk to make the proof self-contained.

"Some computations for connections in generalized geometry"
We look at generalized connections on a Riemannian manifold. We will consider curvature in generalized geometry and look to extend classical computations to the generalized situation.
Zoom meeting: contact Spiro Karigiannis (karigiannis@uwaterloo.ca) or Ragini Singhal (r4singha@uwaterloo.ca) for link.

"Non-minimizing solutions to the Ginzburg-Landau equations"
Sean Monahan, Department of Pure Mathematics, University of Waterloo
We’re starting up an arithmetic geometry seminar, online, and we’d like to include anyone who wants to participate. The starting point will be the book by Hindry and Silverman on Diophantine Geometry, but we may quickly diverge into other directions. I don’t expect this to be the regular meeting time – the most important part of the first meeting will be to decide on a regular meeting time. So if you can’t make it to the organizational meeting, please email David McKinnon to say what your scheduling constraints are.

"Classical and new plumbings bounding contractible manifolds and homology balls"
A central problem in low-dimensional topology asks which homology 3-spheres bound contractible 4-manifolds and homology 4-balls. In this talk, we address this problem for plumbed 3-manifolds and we present the classical and new results together. Our approach is based on Mazur’s famous argument which provides a unification of all results in a fairly simple way.
