In 1993 V. Scheffer produced a nontrivial weak solution of the 2D incompressible Euler equationswith compact support in space-time. Subsequently A.Shnirelman gave different constructionsfor solutions with (i) compact support in time and (ii) strictly decreasing energy. Such 'wild' solutionsseemingly contradict the idea of an evolution equation. ...

The fundamental result of Paouris gives the large deviation estimate for Euclidean norms of log-concave vectors. We extend it to the case of l_r-normsand show that for r>=2, p>=1 the p-th moment of the l_r-norm of a log-concave random vector is comparable to the sum of the first moment and the weak p-th moment up to a constant proportional to r....

I will present a method to prove weak convergence of numerical methods for dynamical systems, using dual solutions. This general method is applied to optimal control problems, and is used to prove convergence of approximate value functions. The theory of large deviations will also be mentioned. It makes it possible to represent rare event soluti...

Joint work with Gil Katz, David Gelman, Mark Ratner and Ronnie Kosloff.Simulation of many body quantum dynamics scales exponentiallybad with the number ofdegrees of freedom. Many methods are devoted to obtain arestricted many body wavefunctionwhich still are able to approximate the quantum dynamics. Inthe context of systembath dynamics the surro...

I will talk about a work in collaboration with G. During and C. Josserand on the long-time evolution of waves of a thin elastic plate in the limit of smalldeformation so that modes of oscillations interact weakly. According to thetheory of weak turbulence (successfully applied in the past to plasma, optics, and hydrodynamic waves), this nonlinea...

This decal was placed on doors around the University of Minnesota Duluth campus. It reads: "Stop The Spread of COVID-19, Wear A Mask If You Are Not Vaccinated Or If You Want To. Support Other Who May Choose To Wear A Mask." The text is red on a gold background. The sign also includes a line drawing of a face mask.

Recently, there has been a rapid rise of on-demand ride-hailing platforms, such as Uber and Didi, which allow passengers with smartphones to submit trip requests and match them to drivers based on their locations and drivers' availability. This increased demand has raised questions about how such a new matching mechanism will affect the efficien...
