Dispersion dynamics for the defocusing generalized Korteweg-de Vries equation
Stefan Steinerberger
We study dispersion for the defocusing gKdV equation. It is expected that it is not possible for the bulk of the mass to concentrate in a small interval for a long time. We s…

Lower bounds on nodal sets of eigenfunctions via the heat flow
Stefan Steinerberger
We study the size of nodal sets of Laplacian eigenfunctions on compact Riemannian manifolds without boundary and recover the currently optimal lower bound by comparing the heat flo…
