Quasi-steady state reduction for the Michaelis-Menten reaction-diffusion system

Martin Frank, Christian Lax, Sebastian Walcher +1

The Michaelis-Menten mechanism is probably the best known model for an enzyme-catalyzed reaction. For spatially homogeneous concentrations, QSS reductions are well known, but this…

Smooth Homogenization of Heat Equations on Tubular Neighborhoods

O. Wittich

We consider the heat equation with Dirichlet boundary conditions on the tubular neighborhood of a closed Riemannian submanifold. We show that, as the tube diameter tends to zero, a…

L2-Homogenization of Heat Equations on Tubular Neighborhoods

O. Wittich

We consider the heat equation with Dirichlet boundary conditions on the tubular neighborhood of a closed Riemannian submanifold. We show that, as the tube radius decreases, the sem…
