Abstract
In this paper, we present a complete solution to the Cauchy dual subnormality problem (for short CDSP) for torally expansive toral 3-isometric weighted 2-shifts. This solution is obtained by solving a couple of Hausdorff moment problems arising from 2-variable polynomials of lower bi-degree.
