Gauge-theoretic moduli spaces are often noncompact, and various techniques have been introduced to study their asymptotic features. Seminal work by Taubes shows that in many situations where the failure of compactness for sequences of solutions is...

Abstract: The Jones polynomial of a knot, discovered in 1983, is a very subtle invariant that is related to a great deal of mathematics and physics. This talk will be an overview of quantum field theories in dimensions 2, 3, 4 and 5 that are...

Mirror symmetry is a duality between symplectic geometry and complex geometry. The homological mirror symmetry (HMS) conjecture was formulated by Kontsevich in 1994 to fully capture this phenomenon for compact Calabi-Yau manifolds. Since then, it has...

The talk is about finite connected 4-valent graphs admitting an edge-transitive and vertex-transitive subgroup \(G\) of automorphisms which preserves an orientation of the edges. But I will first talk about the general approach to describing families...

Associating graphs with groups date back to Arthur Cayley. In this lecture, we will discuss about another graph, called co-maximal subgroup graph Γ( G) introduced by Akbari et al. in [1]. The co-maximal subgroup graph Γ( G) of a group G whose...

Divided power algebras were defined by H. Cartan in 1954 to study the homology of Eilenberg-MacLane spaces. They are commutative algebras endowed, for each integer n, with an additional monomial operation. Over a field of characteristic 0, this...

Abstract. The mathematical modelling of metastasis is a challenge. The occurrence of metastasis is basically random, and the role of the immune response is not at all clear. In this talk I will discuss two models, one for the spatial spread of...

Harary and Sabidussi were the first to study the automorphisms of repeated graphs using the wreath product. Later Hemminger would go on to provide necessary and sufficient conditions for these of repeated automorphisms through the introduction of...

Recent progress in model theory is changing our understanding of how the finite and infinite interact. One aspect of this story has to do with the emerging appearance of complexity in so-called simple unstable theories, which provide a model...
