Abstract: In this article, we present several equivalent conditions ensuring the disjoint supercyclicity of finite weighted pseudo-shifts acting on an arbitrary Banach sequence space. The disjoint supercyclic properties of weighted translations on locally compact discrete groups, the direct sums of finite classical weighted backward shifts, and the bilateral backward operator weighted shifts can be viewed as special cases of our main results. Furthermore, we exhibit an interesting fact that any finite bilateral weighted backward shifts on the space l²(Z) never satisfy the d-Supercyclicity Criterion by a simple proof.

Key words: Disjoint supercyclicity, weighted pseudo-shifts, disjoint Blow-up/collapse Property
