Nearly self-similar blowup of the slightly perturbed homogeneous Landau equation with very soft potentials

Jiajie Chen

We study the slightly perturbed homogeneous Landau equation \[ \partial_t f = a_{ij}(f) \cdot \partial_{ij} f + αc(f) f, \quad c(f) = - \partial_{ij} a_{ij}(f), \] with very soft p…
