Abstract:

Let $X$ be a complex space and $H$ a positive homogeneous plurisubharmonic function $H$ on $X\times \mathbb {C}^m$. Consider the Hartogs-type domain $\Omega _{H}(X):=\{(z,w)\in X\times \mathbb {C}^m:H(z,w)<1 \}$. Let $S$ be an analytic subset of $X$. We give necessary and sufficient conditions for hyperbolicity and tautness modulo $S\times \mathbb {C}^m$ of $\Omega _{H}(X)$, with the obvious corollaries for the special case of Hartogs domains.
