Anomalies, generalized symmetries, and compactifications

• Matteo Sacchi (Univ. Oxford)

Room: Room D Anomalies and symmetries play key roles in understanding QFTs. Compactification, which relates theories in different spacetime dimensions, offers valuable insights as well. In this talk, I will address some aspects of the behaviour of anomalies and generalized symmetries under compactification. I will first explain how the anomalies for finite higher-form symmetries of the lower dimensional theory can be obtained by integrating the anomaly theory of the higher dimensional theory on the compact surface. Then, I will discuss the fate of various generalized symmetry structures (2-group and non-invertible symmetries) in 4d models upon compactification on a 2-sphere. These structures tend to trivialize in 2d, but they can still leave an imprint in terms of ’t Hooft anomalies or symmetry breaking patterns. While tested in supersymmetric models, these concepts are applicable to non-supersymmetric theories too.

Higher Bessel functions: some new results

• Volodya Roubtsov (Univ. Angers)

Room: Room D We consider the generating function $\Phi^{(N)}$ for the reciprocals $N$-th power of factorials (Higher Bessel functions =s olutions $P^{N-1}$ «quantum» DE). We show a connection of product formulas for such series with the periods for certain families of algebraic hypersurfaces. We describe the singular loci of these surfaces and show that they are given by zeros of the Buchstaber-Rees polynomials, entering in $N$-valued group laws. We propose a generalized Frobenius method and use it to obtain special expansions for multiplication kernels in the sense of Kontsevich. Using these expansions we provide some experimental results to connect $N$-Bessel kernels and the hierarchies of the palindromic unimodal polynomials. We study the properties of such polynomials and conjecture positivity of their roots. The results are based on a recent joint paper (arXiv-2405.03015) with I. Gaiur (Toronto) and D. van Straten (Mainz).
