Molecular phylogenetics is concerned with inferring evolutionaryrelationships (phylogenetic trees) from biological sequences (such asaligned DNA sequences for a gene shared by a collection of species).The probabilistic models of sequence evolution that underly statisticalapproaches in this field exhibit a rich algebraic structure.After an introd...

For a graph G, let bc(G) denote the minimum possible number of pairwiseedge disjoint complete bipartite subgraphs of G so that each edge of Gbelongs to (exactly) one of them. The study of this quantity and itsvariants received a considerable amount of attention and is relatedto problems in communication complexity and geometry. After a briefdisc...

Tools from Extremal Graph Theory are helpful in the study of problemsin Additive Number Theory, Theoretical Computer Science, and InformationTheory. I will illustrate this fact by several closely related examplesfocusing on a recent one in a joint work with Moitra and Sudakov.The main combinatorial question addressed, whose study was initiated b...

Configuration spaces of disks in a region of the plane vary according to the radius of the disks, and their topological invariants such as homology also vary. Realizing a given homology class means coordinating the motion of several disks, and if there is not enough space for the disks to move, the homology class vanishes. We explore how cluster...

In NMR spectroscopy, the collective measurement is weakly invasive and its back-action is called radiation damping. The aim of this talk is to provide a control-theoretical analysis of the problem of suppressing this radiation damping. It is shown that the two feedback schemes commonly used in the NMR practice correspond one to a high gain oputp...

An overarching goal of the Langlands program is the principle of functoriality, first formulated in the famous 1967 letter from Langlands to Weil. It roughly states that if the L-groups of two (reductive) groups are related then so are their automorphic spectrum. It has many important consequences including the Ramanujan conjecture for GL(n) as ...

We provide an extension of the theory of flows in Euclidean spaces associated to wekly differentiablevelocity fields, replacing the Euclidean state space with the space of probability measure. This way, thecontinuity equation can be viewed as an ODE in the space of probability measures and we provide somewell-posedness and stability results. We ...
