  In this work, we consider effects of the dynamical vacuum in quantum
cosmology in presence of a minimum length introduced by the GUP (generalized
uncertainty principle) related to the modified commutation relation
$[\hat{X},\hat{P}] := \frac{i\hbar}{ 1 - \beta\hat{P}^2 }$ . We determine the
wave function of the Universe $ \psi_{qp}(\xi,t)$, which is solution of the
modified Wheeler-DeWitt equation in the representation of the quasi-position
space, in the limit where the scale factor of the Universe is small. Although
$\psi_{qp}(\xi,t)$ is a physically acceptable state it is not a realizable
state of the Universe because $ \psi_{qp}(\xi,t)$ has infinite norm, as in the
ordinary case with no minimal length.
