Using a canonical linear embedding of the algebra
${{G}^{\infty }}\left( \Omega \right)$
of Colombeau generalized functions in the space of
$\overline{\mathbb{C}}$
-valued
$\mathbb{C}$-linear maps on the space
$D\left( \Omega \right)$
of smooth functions with compact support, we give vanishing conditions for functions and linear integral operators of class
${{G}^{\infty }}$
. These results are then applied to the zeros of holomorphic generalized functions in dimension greater than one.
