Abstract
A new construction of unilateral discrete shifts of finite multiplicities is presented. This then leads to the generation of a class of shift semigroups of finite multiplicities, in particular, Laguerre shift semigroups over the function spaceL 2 (0, ∞). Moreover, it will be shown that a shift semigroup always has an associated abstract potential operator.
