Title: Towards a Bogomolov-Miyaoka-Yau inequality for symplectic 4-manifolds, II

Abstract: The Bogomolov-Miyaoka-Yau inequality for minimal compact complex surfaces of general type was proved in 1977 independently by Miyaoka, using methods of algebraic geometry, and by Yau, as an outgrowth of his proof of the Calabi conjectures. In this talk, we describe progress in our ongoing program to prove the conjecture that symplectic 4-manifolds obey the Bogomolov-Miyaoka-Yau inequality. Our program uses Morse theory on the gauge theoretic moduli space of non-Abelian monopoles, where the Morse function is a Hamiltonian for a natural circle action and natural two-form. We shall describe generalizations of Donaldson’s symplectic subspace criterion (1996) from finite to infinite dimensions and generalizations of Taubes' perturbation analysis from the Seiberg-Witten to non-Abelian monopole equations. These methods have application to the problem of showing that the fundamental two-form is non-degenerate and thus an almost symplectic form on the moduli space of non-Abelian monopoles. This talk is based on joint work with Tom Leness and the monographs https://arxiv.org/abs/2010.15789 (to appear in AMS Mathematical Surveys and Monographs), https://arxiv.org/abs/2206.14710 and https://arxiv.org/abs/2410.13809 .

Title: Universal Link Invariants via Configuration Spaces

Abstract: Coloured Jones and Alexander polynomials are quantum invariants originating in representation theory and their geometric information is an important open problem in quantum topology. We present a new topological perspective that unifies these invariants through the topology of configuration spaces. First, for a fixed N, we define new link invariants: "N-th Unified Jones invariant" and "N-th Unified Alexander invariant" globalising all coloured Jones and ADO link polynomials of (multi)-colours bounded by N. Asymptotically, Habiro defined his universal knot invariant globalising coloured Jones polynomials by introducing the Habiro ring. For the link case, such globalisation remained open for both sequences of invariants. We answer this problem coming from representation theory using topological tools. On the representation theory side we define extensions of Habiro type rings. On the topological side, we construct a universal Jones link invariant and a universal Alexander link invariant. Putting these together, our universal invariants of geometrical nature take values in the extended Habiro rings that we construct.

Short Talks & Elevator Speeches

In this webinar, we will discuss the most important components of scientific storytelling, namely: how to make a talk focused and engaging; how to present the appropriate amount of data with appealing slide design; how to make the talk personal, memorable, and aid future collaborations - useful tool for conferences and proposals. The webinar is highly interactive so students should come prepared to share selective ideas of their work.

In this seminar, I will present our studies of DNA replication origins from evolutionarily distant bacteria, including Escherichia coli, the hyperthermophile Thermotoga maritima, and the alphaproteobacterium Caulobacter crescentus. Comparison of these species reveals striking differences in origin architecture, providing a unique opportunity to explore how replication initiation systems evolve while maintaining the same fundamental function. By combining biochemical, genetic, and comparative approaches, we uncovered unexpected flexibility in DnaA-dependent origin function.
