Phase space analysis of higher-order dispersive equations with point interactions
Sonia Mazzucchi, Fabio Nicola, S. Ivan Trapasso
We investigate nonlinear, higher-order dispersive equations with measure (or even less regular) potentials and initial data with low regularity. Our approach is of distributional n…
