### A Liouville theorem for plurisubharmonic currents

The goal of this paper is to extend the concepts of algebraic and Liouville currents, previously defined for positive closed currents by M. Blel, S. Mimouni and G. Raby, to psh currents on ${\u2102}^{n}$. Thus, we study the growth of the projective mass of positive currents on ${\u2102}^{n}$ whose support is contained in a tubular neighborhood of an algebraic subvariety. We also give a sufficient condition guaranteeing that a negative psh current is Liouville. Moreover, we prove that every negative psh algebraic current...
