SUMMARY:Christin Bibby: A generating function approach to new representation stability phenomena in orbit configuration spaces
DESCRIPTION:Oberseminar Algebra und Geometrie \nTalk by Christin Bibby (Louisiana State University) \nA generating function approach to new representation stability phenomena in orbit configuration spaces \nAbstract: As countless examples show\, it can be fruitful to study a sequence of complicated objects all at once via the formalism of generating functions. We apply this point of view to the homology and combinatorics of orbit configuration spaces: using the notion of twisted commutative algebras\, which essentially categorify exponential generating functions. This idea allows for a factorization of the orbit configuration space “generating function” into an infinite product\, whose terms are surprisingly easy to understand. Beyond the intrinsic aesthetic of this decomposition and its quantitative consequences\, it reveals a sequence of primary\, secondary\, and higher representation stability phenomena. This is joint work with Nir Gadish.

SUMMARY:Tyler Kelly: An Open Enumerative Theory for Landau-Ginzburg models.
DESCRIPTION:Oberseminar Algebra und Geometrie \nTalk by Tyler Kelly (Birmingham) \nAn Open Enumerative Theory for Landau-Ginzburg models. \nAbstract: Landau-Ginzburg models consist of a pair (W\, G) where W is a potential (that is\, a complex valued regular function from a quasi-affine variety X) and G is a group acting on X so that W is invariant. In the context of mirror symmetry\, oftentimes they can be viewed as a noncommutative symplectic deformation of a symplectic manifold. Over the past couple of decades there has been work in establishing an enumerative theory for a Landau-Ginzburg model\, akin to Gromov-Witten theory. Recently\, a few of us have aimed to create an open enumerative theory for Landau-Ginzburg models. In the end\, we can construct the mirror Landau-Ginzburg model’s potential function as a generating function of open enumerative invariants. This provides the Landau-Ginzburg analogue to Maslov index two discs / tropical discs for a symplectic manifold. This is joint work with Mark Gross and Ran Tessler.

SUMMARY:Uniform bounds for torsion packets on tropical curves
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (First meeting Winter Semester 2021/22) \nHarry Richman (University of Washington) \nAbstract:\nSay two points x\, y on an algebraic curve are in the same torsion packet if [x – y] is a torsion element of the Jacobian. In genus 0 and 1\, torsion packets have infinitely many points. In higher genus\, a theorem of Raynaud states that all torsion packets are finite. It was long conjectured\, and only recently proven*\, that the size of a torsion packet is bounded uniformly in terms of the genus of the underlying curve. We study the tropical analogue of this construction for a metric graph. On a higher genus metric graph\, torsion packets are not always finite\, but they are finite under an additional “genericity” assumption on the edge lengths. Under this genericity assumption\, the torsion packets satisfy a uniform bound in terms of the genus of the underlying graph. (*by Kuehne and Looper-Silverman-Wilmes in 2021)

SUMMARY:Applications of tropical geometry to irreducibility problems in algebraic geometry
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (First meeting Winter Semester 2021/22) \n15:15-16:15 Ilya Tyomkin (Ben Gurion University) \nAbstract:\nIn my talk\, I will discuss a novel tropical approach to classical irreducibility problems of Severi varieties and of Hurwitz schemes. I will explain how to prove such irreducibility results by investigating the properties of tropicalizations of one-parameter families of curves and of the induced maps to the tropical moduli space of parametrized tropical curves. The talk is based on a series of joint works with Karl Christ and Xiang He.

SUMMARY:Orders and polytropes: matrices from valuations
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (First meeting Winter Semester 2021/22) \n14:00-15:00 Mima Stanojkovski (RWTH Aachen) \nAbstract:\nLet K be a discretely valued field with ring of integers R. To a d-by-d matrix M with integral coefficients one can associate an R-module\, in K^{d x d}\, and a polytope\, in the Euclidean space of dimension d-1. We will look at the interplay between these two objects\, from the point of view of tropical geometry and building on work of Plesken and Zassenhaus. This is joint work with Y. El Maazouz\, M. A. Hahn\, G. Nebe\, and B. Sturmfels. \n

SUMMARY:Oishee Banerjee: Filtration of cohomology via symmetric (semi-)simplicial spaces
DESCRIPTION:Oberseminar Algebra und Geometrie \nTalk by Oishee Banerjee (University of Bonn) \nFiltration of cohomology via symmetric (semi-)simplicial spaces \nAbstract: Inspired by Deligne’s use of the simplicial theory of hypercoverings in defining mixed Hodge structures we replace the indexing category ∆ by the symmetric simplicial category ∆S and study (a class of) ∆S-hypercoverings\, which we call spaces admitting symmetric (semi)simplicial filtration. For ∆S-hypercoverings we construct a spectral sequence\, somewhat like the Cˇech-to-derived category spectral sequence. The advantage of working on ∆S is that all of the combinatorial com- plexities that come with working on ∆ are bypassed\, giving simpler\, unified proof of known results like the computation of (in some cases\, stable) singular cohomol- ogy (with rational coefficients) and étale cohomology (with Q_l coefficients) of the moduli space of degree n maps C to a projective space \, C a smooth projective curve of genus g\, of unordered configuration spaces\, that of the moduli space of smooth sections of a fixed gdr that is m-very ample etc.

SUMMARY:Dr. Marcin Lara: Specialization for the pro-étale fundamental group and fundamental groups in rigid geometry
DESCRIPTION:The specialization morphism for the étale fundamental groups of Grothendieck cannot be generalized word-for-word to the more general pro-\’etale fundamental group of Bhatt and Scholze. \nIt turns out\, that one can deal with this problem by applying a rigid-geometric point of view: for a formal scheme X of finite type over a complete rank one valuation ring\, we construct a specialization morphism \nfrom the de Jong fundamental group of the rigid generic fiber to the pro-étale fundamental group of the special fiber.  The construction relies on an interplay between admissible blowups of X and normalizations of the irreducible components of X_k\, and employs the Berthelot tubes of these irreducible components in an essential way. \nI will also mention a generalization of the de Jong’s fundamental group. It is defined using a notion of “geometric arcs” in rigid geometry\, enjoys many good properties of the pro-étale fundamental group and allows to answer some old questions of de Jong. This is a joint work with Piotr Achinger and Alex Youcis.

SUMMARY:Georg Tamme (Universität Mainz): Purity in chromatically localized algebraic K-theory
DESCRIPTION:In classical algebra\, the prime fields are Q and for every prime number p the finite field F_p. In higher algebra\, one has for every prime number p an additional sequence of prime fields K(p\,n)\, n a natural number\, which in some sense interpolates between Q and F_p. Associated with these prime fields one has corresponding localization and completion functors. An interesting question\, raised by Waldhausen and Ausoni—Rognes\, is how these functors interact with algebraic K-theory. In the talk I will first give an introduction and discuss a purity result for algebraic K-theory with respect to these completion functors. This is based on joint work with Markus Land\, Akhil Mathew\, and Lennart Meier and on closely related work of Dustin Clausen\, Akhil Mathew\, Niko Naumann\, and Justin Noel.
