Uniform null-controllability times for the Coron--Guerrero problems are $2$ and $2 + 22$

Kai Koike, Vincent Laheurte

We study the uniform null-controllability, in the vanishing viscosity limit, of the transport--diffusion equation $u_{t} + M u_{x} = ε u_{xx}$ on $[0, L]$ with a Dirichlet bou…

Optimal error estimates for the half-way bounce-back lattice Boltzmann method for the Stokes equations

Kai Koike

We give a mathematical proof of the optimal convergence rates for the D2Q9 BGK lattice Boltzmann method with the half-way bounce-back rule for the incompressible Stokes equations i…
