Conditional integrability and stability for the homogeneous Boltzmann equation with very soft potentials

Abstract

We introduce a practical criterion that justifies the propagation and appearance of LpL^{p}-norms for the solutions to the spatially homogeneous Boltzmann equation with very soft potentials without cutoff. Such criterion also provides a new conditional stability result for classical solutions to the equation. All results are quantitative. Our approach is inspired by a recent analogous result for the Landau equation derived in arXiv:2306.15729 and generalises existing conditional results related to higher integrability properties and stability of solutions to the Boltzmann equation with very soft potentials.
