Finite time singularities in the Landau equation with very hard potentials

Jacob Bedrossian, Jiajie Chen, Maria Pia Gualdani +3

We consider the inhomogeneous Landau equation with ${\hat{I}}^3\in (\sqrt{3},2]$ and construct smooth, strictly positive initial data that develop a finite time singularity. The $C^{\hat{I}}\pm$-norm…
