We will outline a possible approach to outstanding computationalcomplexity theory (CCT) questions. The approach relies on a faithful mapping of these questions to questions in geometric invariant (GIT)theory and representation theory. We begin with a construction of Valiant and show its connection to the Orbit Closure and Membership problems in ...

Now that optimal transport algorithms are reaching new levels of sophistication, we can turn our attention to developing mature applications of transport in machine learning and statistics. In this talk, I will demonstrate the breath of applications in which we can incorporate machinery from transport, as well as the computational techniques nee...

We discuss bacterial biofilms and the scope for describing their viscoelastic mechanical properties as a consequence of their underlying polymeric and multiphase morphology. Biofilms are the most prevalent phenotype of bacteria in nature. Biofilms form under conditions common in industry and in the body. They are structurally heterogeneous on mu...

Let A be a finite set of integers. The sum set, A+A, is the setof pairwise sums from A and the product set, AA, is the set of pairwiseproducts. Erdos and Szemeredi conjectured that either the sum set or theproduct set should be large, A+A+AA is (almost) quadratic in A forany subset of integers. This problem (and some of its variants) became oneo...

Our understanding of the working brain is partly based on observations through the "windows of the brain", electric (EEG/MEG), metabolic (PET), or hemodynamic (fMRI,OT). To shed light on the intricacies of the neurovascular coupling, and in order to model phenomena such as CSD, it is important to work towards an integrated model of the three key...

When observed data are used to infer on parameters that are not directly observable, usually an inverse problem needs to be solved. Characteristic for inverse problems is their ill-posedness, which in practice means that small errors in data may propagate to huge inconsistencies in the solution if the problem is not properly regularized or augme...

Identification of subgroups in a biomedical study with subjects sampled from a heterogeneous population has attracted considerable attention in recent years. Technically, subgroup group analysis may be formulated as a type of supervised clustering analysis with group labels being latent. The method of finite mixture model is the most widely used...

Formally, exit problem with an alpha-stable process is associated with an elliptic PDE with Dirichlet boundary and fractional Laplacian operator. We will investigate sufficient conditions of the exit problem value to be the strong, respectively generalized viscosity solution of its associated Dirichlet problem. Solvability of parabolic PDE can a...

We investigate the applicability of electron cryomicroscopy (cryo-EM) with single particle reconstruction in the RNA structural studies as small as 154 residues (~50 kD). This size is at least two-fold smaller than the generally conceived limits for single-particle image reconstruction by cryo-EM of macromolecules. For the Specificity and Cataly...

The Szemeredi regularity lemma is crucial in graph limit theory.It isa basic tool to study large dense graphs: e.g. how to consider similarity,approximation by small graphs, how local and global properties are related to each other. It provides important new bridge between graph theoryand other fields like analysis, probability, topology.Focusin...

In 1980, Askold Khovanskii established his fewnomial bound forthe number of real solutions to a system of polynomials, thereby showing thatthe complexity of real solutions to a polynomial system depends upon the numberof monomials and not the degree. This fundamental finiteness result in realalgebraic geometry was proven by induction on the numb...
