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...

Abstract: Given a family G of graphs on a common vertex set X, we say that G is rainbow connected if for every vertex pair u, v ∈ X, there exists a path from u to v that uses at most one edge from each graph of G. We consider the case that G contains...

The activation of T cells, key players of the immune system, involves local evacuation of molecules (phosphatases) from the nearby region of the cell surface, segregating them from the T cell receptor. What drives this evacuation? This phenomenon...

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...

Abstract: The generalized Lotka-Volterra (gLV) equations describe the population dynamics of a set of interacting species, and are a classic model in theoretical ecology. As the number of species in these systems grow in number, their dynamics become...

The tumor invasion paradox relates to the artifact that a cancer that is exposed to increased cell death (for example through radiation), might spread and grow faster than before. The presence of cancer stem cells can convincingly explain this effect...

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...

One of the challenges of the accurate simulation of turbulent flows is that initial data is often incomplete. Data assimilation circumvents this issue by continually incorporating the observed data into the model. A new approach to data assimilation...

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...
