To overcome the lack of strong a priori estimates and to define a meaningful collision operator, we introduce a notion of renormalized solution which enables us to establish stability results for sequences of solutions and global existence for the Cauchy problem with large data.

Webclass of terms from this expansion and argued that it gives the Boltzmann equation. To the second order in the coupling constant, Hugenholtz’s claim was proved by Ho and Landau [6]. Beyond that it is not even clear that these terms satisfy the Boltzmann equation order by order, partly due to the complicated selection rules. WebHá 1 dia · This work deals with the non-cutoff Boltzmann equation with hard potentials, in both the torus $\mathbf{T}^3$ and in the whole space $\mathbf{R}^3$, under the incompressible Navier-Stokes scaling. Web9 de abr. de 2024 · Abstract A method for solving the Boltzmann equation is presented that makes it possible to calculate gas flows in the continuum flow regime described by the Navier–Stokes equations. Progress into the region of continuum flows was achieved by applying the conservative projection method for calculating the Boltzmann collision … fity bright
