    This is the first in a series of introductory lectures in descriptive set theory, following Matt Foreman's expository paper. The topics discussed will be basics of Polish topologies, product topologies, Cantor space and Baire space, and infinite trees.

    In this session, we will cover the use of active learning techniques in the classroom to engage students in the learning process. We will begin with a short discussion on considerations for active learning, followed by how to create buy-in for students. Afterwards, we will go over different techniques depending on content goals and group sizes. We...

    The class group is a natural abelian group one can associate to a number field, and it is natural to ask how it varies in families. Cohen and Lenstra famously proposed a model for families of quadratic fields based on random matrices of large rank, and this was later generalized by Cohen-Martinet. However, their model was observed by Malle to have...

    We will discuss the recent work by Rifkind and Virag concerning the shape of eigenvectors for the one-dimensional critical random Schrodinger operator.  https://arxiv.org/abs/1605.00118

    I will discuss a new construction of families of Ricci-flat Kahler metrics on K3 surfaces which collapse to an interval, with Tian-Yau and Taub-NUT metrics occurring as bubbles. There is a corresponding singular fibration from the K3 surface to the interval, with regular fibers diffeomorphic to either 3-tori or Heisenberg nilmanifolds. This is...

    Most biological experiments result in snapshots that illustrate select aspects of a phenomenon of interest. These snapshots may be very complicated, consisting of thousands of peaks in a mass spectrogram, the expression levels of whole genomes, or an impressive image visualizing the localization of different proteins. Yet, each result is...
