Sup-norm estimates for parabolic systems with dynamic boundary   conditions
  We consider parabolic systems with nonlinear dynamic boundary conditions, for which we give a rigorous derivation. Then, we give them several physical interpretations which includes an interpretation for the porous-medium equation, and for certain reaction-diffusion systems that occur in mathematical biology and ecology. We devise several strategies which imply (uniform)}$L^{p} and}$L^{\infty}$ estimates on the solutions for the initial value problems considered.
