Low-regularity well-posedness for dispersive equations with derivative nonlinearity and quasi-periodic initial data

Robert Schippa

We show low-regularity well-posedness of the Korteweg-de Vries equation with spatially quasi-periodic initial data. To this end, we employ frequency-dependent time localization and…

Local smoothing for rough wave equations

Jan Rozendaal, Robert Schippa

We prove local smoothing estimates for wave equations with coefficients, relying on bilinear restriction estimates associated with rough wave propagation. In two and three…
