| Research Abstract |
We studied the large time behavior of positive solutions for the Laplace equation with a nonlinear dynamical boundary condition and for a nonlinear elliptic equation with a dynamical boundary condition, in a half space. We identified a critical exponent for the global existence of positive solutions and showed that small solutions behave likesuitable multiples of the Poisson kernel.
