This talk is motivated by some recent work of Bourgain- rezis-Mironescu. A few years ago, they introduced an elementary way of defining the Sobolev spaces $W^{1,p}$ without making any use of derivatives. I will present their definition and some...

We'll start by exhibiting volume-minimizing properties for certain isotropic submanifolds in complex projective spaces via integral geometry. This will lead us to a problem of finding the infimum of areas for isotropic surfaces with a given boundary...

We introduce a new graph parameter, called the rothendieck constant of a graph. This parameter is a generalization of the classical Grothendieck constant; and it is equal to an integrality gap of a certain SDP problem, which has various algorithmic...

We study the parallel time-complexity of basic cryptographic primitives such as one-way functions (OWFs) and pseudorandom generators (PRGs). Specifically, we consider the possibility of computing instances of these primitives by NC0 circuits, in...

In a sequence of preprints M. Gromov introduced a new model of a random quotient of a finitely generated group and indicated that under favourable conditions the quotient groups should be non-trivial and satisfy Kazhdan's Property (T), both with...
