Query: Pure Semigroups of Isometries on Hilbert C*-Modules   We show that pure strongly continuous semigroups of adjointable isometries on
a Hilbert C*-module are standard right shifts. By counter examples, we
illustrate that the analogy of this result with the classical result on Hilbert
spaces by Sz.-Nagy, cannot be improved further to understand arbitrary isometry
semigroups of isometries in the classical way.
