Winter school on Cremona groups, geometric topology and algebraic geometry
06 Jan 2020 - 10 Jan 2020 • Cuernavaca, Mexico
Instituto de Matematicas UNAM in Cuernavaca
The goal of the school is to discuss some topics in the interaction between Group Theory, Geometric Topology, and Algebraic Geometry, with particular emphasis in the theory of Cremona groups and its recent developments. It will be directed mainly toward graduate students and young postdocs.

Advances in Mixed Characteristic Commutative Algebra and Geometric Connections
07 Jun 2020 - 12 Jun 2020 • Oaxaca, Mexico
Banff International Research Station for Mathematical Innovation and Discovery
One of the big ideas in modern mathematics is that integers (like 1, 2, 3, 4, 5, ...) in many formal ways behave similarly to polynomial equations (like y = x^2, which defines the parabola). Frequently, and perhaps surprisingly, many questions in mathematics are easier to study for polynomials than for integers. Hence intuition and results for polynomials can tell us about the integers. Commutative algebra lives at the intersection of both perspectives, and one fundamental object of study is polynomials with integer coefficients, this is called the mixed characteristic case. Recently, Yves Andre proved a long standing open conjecture in commutative algebra in this mixed characteristic setting, relying on constructions of Scholze (and then Bhatt gave a simplified proof of the same conjecture). This workshop aims to foster and discuss these and other recent tools, to study some remaining open problems in mixed characteristic. The workshop will bring together a diverse group of researchers from different fields, such as commutative algebra, algebraic geometry, and number theory.
