Cat Wilson is the Graduate Student Career Development Advisor at Career Services. She will present on what kind of information to include on your CV or resume, what language to use, and how to use formatting to your advantage.
I will recall the definition of a -correspondence and of the Cuntz-Pimsner algebra. I will discuss group actions on -correspondences and crossed products. I will illustrate with examples related to graphs and to vector bundles.

In this talk, we consider the matrix model Y=S+X where S is a low-rank deterministic matrix, representing the signal, and X is a random noise. It is a central task in high dimensional data analysis to understand how the spectral properties of S are altered with a small random perturbation. We give a precise description of the limiting distribution of the angles between the outlier singular vectors of Y with their counterparts, the leading singular vectors of S. It turns out that the limiting distribution depends on the structure of S and the distribution of X, and thus it is non-universal. This talk is based on a joint work with Zhigang Bao and Xiucai Ding.
