Title: Counting Tensor Invariants with Defect TQFT

Abstract: A tensor transforming under a unitary-orthogonal symmetry group carries finitely many invariant observables of each degree. Counting these so-called tensor invariants is an important problem in the theory of tensor models, and it reduces to counting tuples of permutations modulo a conjugation action.

In this talk, I will explain how this counting can be interpreted as the partition function of an untwisted Dijkgraaf-Witten topological quantum field theory with defects. The permutations groups appearing in the tensor invariant counting problem are exactly the defect data of a stratified manifold, and the tensor invariant is then the groupoid cardinality of the associated gauge groupoid. I conclude with physics applications coming from this perspective of tensor invariants.

This talk is based on forthcoming joint work with Remi Cocou Avhou, Noan Botcazou-Brasse, and Reiko Toriumi.

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.
