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...

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...

We Are Water: the University and Minnesota's Water Future. Almost reflexively, Minnesotans say they are proud of the state's waters. Visits up to the lake are cherished parts of many lives and the state walleye fishing opener is practically a state holiday. Yet 41% of the state's waters are impaired, and failing water systems will cost billions ...

The "Un sac de Billes" Lithographs are based on French Holocaust survivor, Joseph Joffo's (1931-) memoir "Un sac de Billes" (A Bag of Marbles) published in 1973. The book is based on Joffo and his brother's experience during World War II, after their father gives them 5000 francs and instructions to flee Nazi-occupied Paris and, somehow, get to ...
