Abstract
We consider the equation \Deltau = 0 posed in Q := (0;+\infty) \times \Omega ; \Omega:=\{x = (x'; x_ N)/ x' \in R^{N-1}; x_N > 0\}; with the dynamical boundary conditionB(t, x',0)u_{tt} + A(t, x',0)u_t - u_{x_N} \geq D(t; x',0; 0) |u|^q on \Sigma := (0;\infty) \times R^{N-1} \times \{0\} and give conditions on the coefficient functions A(t, x',0); B(t, x',0; 0) and D(t, x'; 0) for the nonexistence of global solutions.
