Shift invariant subspaces of slice L^2 functions / A. Monguzzi, G. Sarfatti. - In: ANNALES ACADEMIAE SCIENTIARUM FENNICAE. MATHEMATICA. - ISSN 1239-629X. - 43(2018), pp. 1045-1061. [10.5186/aasfm.2018.4366]
Abstract:
In this paper we characterize the closed invariant subspaces for the (*-)multiplier operator of the quaternionic space of slice L2 functions. As a consequence, we obtain the inner-outer factorization theorem for the quaternionic Hardy space on the unit ball and we provide a characterization of quaternionic outer functions in terms of cyclicity.
