SUMMARY:Vertex gluings and Demazure products
DESCRIPTION:Oberseminar Algebra und Geometrie \nNathan Pflueger (Amherst College) \nAbstract:\nFinite graphs and metric graphs provide useful combinatorial analogs of algebraic curves. Since the work of Cools-Draisma-Payne Robeva\, it has been known that chains of loops are particularly useful graphs in this regard. I will describe a new perspective on these chains of loops\, by describing a version of Brill-Noether theory for curves or graphs with two marked points. Divisors on twice-marked graphs are associated with permutations; the extent to which a divisor is special is measured by the inversions of the permutation. This twice-marked Brill-Noether theory is well-suited to inductive arguments; when two twice-marked graphs are glued together\, permutations are combined by an operation called the Demazure product. I will describe how this framework provides a short proof of some of the results of Cools-Draisma-Payne Robeva\, as well as more recent results on tropical Hurwitz-Brill-Noether theory\, and may provide a route to identifying new classes of Brill-Noether-General graphs.

SUMMARY:The S_n action on the homology groups of M_{0\,n}-bar
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (Second meeting) \nRohini Ramadas (University of Warwick) \nAbstract:\nThe symmetric group on n letters acts on M_{0\,n}-bar\, and thus on its (co-)homology groups. The induced actions on (co-)homology have been studied by\, eg.\, Getzler\, Bergstrom-Minabe\, Castravet-Tevelev. We ask: does H_{2k}(M_{0\,n}-bar) admit an equivariant basis\, i.e. one that is permuted by S_n? We describe progress towards answering this question. This talk includes joint work with Rob Silversmith.

SUMMARY:Cut-and-paste invariants of moduli spaces of relative stable maps to P^1
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (Second meeting) \nSiddarth Kannan (Brown University) \nAbstract:\nI will discuss ongoing work studying moduli spaces of genus zero stable maps to P^1\, with fixed ramification profiles over 0 and infinity. I will describe a chamber decomposition of the space of ramification data such that the Grothendieck class of the moduli space is constant on the chambers. Finally\, for the sequence of ramification data corresponding to maximal ramification over 0 and no ramification over infinity\, I will describe a recursive algorithm to compute the generating function for Euler characteristics of these spaces.

SUMMARY:Patchworks of real algebraic varieties in higher codimension
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (Second meeting) \nJohannes Rau (Universidad de los Andes) \nAbstract:\nI will present a combinatorial setup\, based on smooth tropical varieties and real phase structures\, which after “unfolding” produces a certain class of PL-manifolds (called patchworks). We have two motivations in mind: Firstly\, in the spirit of Viro’s combinatorial patchwoking for hypersurfaces\, these patchworks can be used to describe the topology of real algebraic varieties close to the tropical limit. Secondly\, even if not “realisable” by real algebraic varieties\, real phase structures provide a geometric framework for combinatorial structures such as oriented matroids. Joint work with Arthur Renaudineau and Kris Shaw.

SUMMARY:Dissipation of Correlations of Automorphic Forms
DESCRIPTION:Oberseminar Algebra und Geometrie \nPetru Constantinescu (MPIM Bonn) \nAbstract:\nMass equidistribution of eigenfunctions is a central topic in quantum chaos and number theory. In this talk we highlight a generalisation of the Quantum Unique Ergodicity for holomorphic cusp forms in the weight aspect. We show that correlations of masses coming from off-diagonal terms dissipate as the weight tends to infinity. This corresponds to classifying the possible quantum limits along any sequence of Hecke eigenforms of increasing weight.

SUMMARY:Graph potentials\, TQFTs and mirror partners
DESCRIPTION:Oberseminar Algebra und Geometrie \nTalk by Pieter Belmans (Université du Luxembourg) \nGraph potentials\, TQFTs and mirror partners \nAbstract: In a joint work with Sergey Galkin and Swarnava Mukhopadhyay we introduced a class of Laurent polynomials associated to decorated trivalent graphs which we called graph potentials. These Laurent polynomials satisfy interesting symmetry and compatibility properties\, leading to the construction of a topological quantum field theory which efficiently computes the classical periods as the partition function. \nUnder mirror symmetry graph potentials are related to moduli spaces of rank 2 bundles (with fixed determinant of odd degree) on a curve of genus $g\geq 2$\, which is a class of Fano varieties of dimension $3g-3$. I will discuss how enumerative mirror symmetry relates classical periods to quantum periods in this setting. Time permitting I will touch upon aspects of homological mirror symmetry for these Fano varieties and their mirror partners.

SUMMARY:Hodge theory of matroids (Session 6) / CRC-Colloquium
DESCRIPTION:This semester’s topic in our joint research seminar is Hodge theory of matroids. The meetings take place on Zoom on a bi-weekly basis during lecture time\, Thursdays 15-18. \nTalk 11: June Huh (Princeton University): Kazhdan-Lusztig and singular Hodge theory for matroids \nAbstract: There is a remarkable parallel between the theory of Coxeter groups (think of the symmetric group or the dihedral group) and matroids (think of your favorite graph or vector configuration). After giving an overview of the similarity\, I will report proofs of two combinatorial conjectures\, the nonnegativity conjecture for Kazhdan-Lusztig coefficients and the top-heavy conjecture for the number of flats of matroids. The key step is to formulate and prove an analogue of the decomposition theorem for a resolution of singularities in a combinatorial setup\, which is closely related to the validity of the hard Lefschetz theorem and the Hodge-Riemann relations for what would be an intersection Chow cohomology in realizable cases. The talk should be enjoyable without specialized knowledge. Joint work with Tom Braden\, Jacob Matherne\, Nick Proudfoot\, and Botong Wang.
