Abstract: This paper is concerned with the following Gierer-Meinhardt type systems subject to Dirichlet boundary conditions:

$\displaystyle \left\{\begin{tabular}{ll} $\displaystyle\Delta u- \alpha u +\fra... ...yle u=0,\; v=0$ \quad & $\mbox{\rm on } \partial\Omega,$ \end{tabular} \right. $

where $ \Omega\subset\mathbb{R}^N$ ($ N\geq 1$) is a smooth bounded domain, $ \rho(x)\geq 0$ in $ \Omega$ and $ \alpha,\beta\geq 0$. We are mainly interested in the case of different source terms, that is, $ (p,q)\neq (r,s)$. Under appropriate conditions on the exponents $ p,q,r$ and $ s$ we establish various results of existence, regularity and boundary behavior. In the one dimensional case a uniqueness result is also presented.
