Coisometries with a prescribed asymptotic modular ratio

The finite-site constructions give genuine coisometries. Their modular ratios converge to an arbitrary number in the open unit interval, and their conjugations converge strongly to the identity.

    Source documentation

    A converging state ratio gives the corresponding approximate modular vector equation for every uniformly contractive coisometry sequence.
