A course on modern sieve theory:

"Sieving in algebra and geometry"

This course explores recent advances in the application of classical methods from analytic number theory—such as Brun’s sieve, the large sieve, and the Hardy–Littlewood circle method—to problems in algebraic number theory and arithmetic geometry.

Emphasis will be placed on the interplay between analytic techniques and geometric structures, with applications including the Cohen–Lenstra heuristics in the statistical study of class groups and the Batyrev–Manin conjecture on the distribution of rational points on Fano varieties. No prior familiarity with sieves will be assumed.

MPIM seminar room on:
Monday 12 May, time 16.30-17.30
Tuesday 13 May, time 16.30-17.30
Wednesday 14 May, time 16.30-17.15

Lecture 10: Dualizable categories and localizing motives, V

I will give an introduction to localizing invariants of dualizable categories. I will start with the general theory of dualizable categories, and explain some non-trivial results, such as equivalence between dualizability and flatness for a presentable stable category. Then we will compute the localizing invariants of various dualizable categories which come from topology and non-Archimedean analysis. These include sheaves on locally compact Hausdorff spaces and categories of nuclear modules on formal schemes. I will also explain a deep connection between the algebra of dualizable categories and the category of localizing motives -- the target of the universal finitary localizing invariant (of categories over some base). We will see that the category of localizing motives (considered as a symmetric monoidal category) is in fact rigid in the sense of Gaitsgory and Rozenblyum, and sketch some applications of this result.

Abstract:

At the start of the 20th century, David Hilbert asked which representations can arise by studying the monodromy of Fuchsian equations. This question was the starting point for a beautiful circle of ideas relating the topology of a complex algebraic variety X to the study of algebraic differential equations. A central result is the celebrated Riemann-Hilbert correspondence of Kashiwara and Mebkhout, which supplies a fully faithful embedding from the category of perverse sheaves on $X$ to the category of algebraic $\mathfrak{D}_X$-modules. This embedding is transcendental in nature: that is, it depends essentially on the (archimedean) topology of the field of complex numbers. It is natural to ask if there is some counterpart of the Riemann-Hilbert correspondence over nonarchimedean fields, such as the field $\mathbf{Q}_p$ of $p$-adic rational numbers. In this series of lectures, I will survey some of what is known about this question and describe some recent progress, using tools from the theory of prismatic cohomology (joint work with Bhargav Bhatt).
