#### Murphy's law in Hilbert scheme

###### Sungwoo Nam (Illinois Math)

Abstract: One feature of moduli space is that although it parametrizes nice objects like smooth projective curves, it can be quite bad. In this talk, we will see lots of instances of these phenomena(mostly involving lots of cohomology computations) focusing on Hilbert scheme of curves in a projective space. I'll end with a discussion on Mumford's famous pathological example and Murphy's law formulated by Vakil.

#### Global climate change, regional climate impacts, and quantifying relevant uncertainties

###### Ryan Sriver (University of Illinois, Atmospheric Sciences)

Abstract: Earth is warming, and the damages associated with climate and weather extremes (droughts, heatwaves, hurricanes) are increasing. Projecting these changes into the future is difficult due to: incomplete understanding of the physical processes, inadequate numerical models and resolution, and relatively short observational records. Here we highlight some of the current grand climate change problems, and we present some of our group's recent work in areas related to climate extremes and uncertainty quantification surrounding projections of future climate change.

#### "Generic representations of abelian groups and extreme amenability" by J. Melleray and T. Tsankov (Part 1)

###### Dakota Ihli (UIUC)

Abstract: In this series of talks, we discuss the paper in the title [arXiv link].

#### Systems of Calogero-Moser Type

###### Matej Penciak (Illinois Math)

Abstract: It is well known that many-particle systems are in general not solvable analytically. For some specific choices of interactions between particles though, a lot can be said. In this talk I aim to give an introduction to systems of Calogero-Moser type and the surprising role of algebraic geometry in their solvability. I will also give a perspective on how this subject plays a role in some hot topics in mathematics in general: Hitchin integrable systems, geometric representation theory, and the geometric Langlands philosophy.
