SUMMARY:Film Screening:Sky Tonight
DESCRIPTION:A live presentation on what to find in the sky tonight and for the coming few weeks. This presentation includes how to find the cardinal directions with the North Star\, current and upcoming constellations\, visible planets\, a few deep sky objects depending on the season\, and other interesting astronomical visualizations. If you want to be able to look up from your own backyard and know what to look for\, this is the show for you.

SUMMARY:Workshop / Seminar:Student Algebraic Geometry: Etale Homotopy and Higher Obstructions to Rational Points
DESCRIPTION:The étale topology on schemes is a testament to the influence of algebraic topology on algebraic geometry. Étale realizations of topological invariants\, such as the fundamental group and singular cohomology\, played a central role in the development of french-school algebraic geometry. This exposé will tell the story of the étale homotopy type of a scheme\, which provides a general framework for realizing homotopy-theoretic constructions in étale algebraic geometry. As an application of this\, I will present an obstruction theory for finding rational points on varieties. At the level of $\pi_1$ this theory will recover classical obstructions due to Grothendieck. I'll conclude with the question of exhibiting explicit examples in which the classical $\pi_1$-obstruction vanishes\, but higher obstruction classes prevent the existence of rational points.

SUMMARY:Workshop / Seminar:Zamolodchikov Periodic Cluster Algebras
DESCRIPTION:In 2007\, Fomin and Zelevinsky introduced the bipartite belt\, a sequence of bipartite cluster mutations whose exchange relations form a discrete dynamical system. When the system is periodic\, we call this Zamolodchikov periodicity. In this talk\, we discuss the classification of all Zamolodchikov periodic cluster algebras\, with connections to W-graphs\, root systems\, and maximal green sequences. We observe that there is a natural red-blue statistic on the associated tropical dynamics that is homomesic\, and use laminations to prove it for finite type. This gives a natural bijection between colored mutations in the dynamical system and roots in the associated root system.
