The Monge transfer problem goes back to the 18th century. It consists in minimizing the transport cost of a material from a place to another (and changing the shape). Monge could not solve the problem and the next significant step was achieved 150...

For a given $\epsilon > 0$, we say that a graph $G$ is $\epsilon$-flexibly $k$-choosable if the following holds: for any assignment $L$ of lists of size $k$ on $V(G)$, if a preferred color is requested at any set $R$ of vertices, then at least $...

Mechanical forces play an essential role in development, most evidently as the drivers of morphogenesis, but also potentially as long-range signals contributing to embryonic self-organization. Regulative development is particularly evident in...

We prove that skew systems with a sufficiently expanding base have "approximate" statistical properties similar to random ergodic Markov chains. For example, they exhibit approximate exponential decay of correlations, meaning that the exponential...

Abstract:A set of geometric graphs is geometric-packable if it can be asymptotically packed into every sequence of drawings of the complete graph K_n. For example, the set of geometric triangles is geometric-packable due to the existence of Steiner...

Abstract: Multi-marginal optimal transport in the general mathematical problem of aligning several probability distributions with maximal efficiency, relative to a given cost function. While many applications for this problem have emerged over the...

The Erdos-Hajnal conjecture states that for every graph H there exists $c > 0$ such that every n-vertex graph $G$ either contains $H$ as an induced subgraph, or has a clique or stable set of size at least $n^c$. I will talk about a proof of this...

Abstract: We study stochastic motion of objects in micrometer-scale living systems: proteins in the nucleus, organelles in cells, and pathogens in mucus barriers. Phenomena such as self organization emerges from the behavior of single individuals...

Quantum State Transfer on Graphs

Quantum computing is believed to provide many advantages over traditional computing, particularly considering the speed at which computations can be performed. One of the challenges that needs to be resolved in order to construct a quantum computer...

Abstract: Motivated by biological questions related to DNA packing and the movement of molecules through channels, it is of interest to determine whether a specific knot or link type can be realized in a confined volume. In this talk, we will discuss...
