Abstract

In resonance to a recent geometric framework proposed by Dou- glas and Yang, a functional model for certain linear bounded operators with rank-one self-commutator acting on a Hilbert space is developed. By taking ad- vantage of the rened existing theory of the principal function of a hyponormal operator we transfer the whole action outside the spectrum, on the resolvent of the underlying operator, localized at a distinguished vector. The whole con- struction turns out to rely on an elementary algebra body involving analytic multipliers and Cauchy transforms. A natural eld
