Necessary conditions on the support of RP-measures
Linus Bergqvist
We give necessary conditions for when a subset of can contain the support of some non-zero RP-measure. Among other things we show that the support of a positive RP-m…
Clark measures for rational inner functions II: general bidegrees and higher dimensions
John T. Anderson, Linus Bergqvist, Kelly Bickel +2
We study Clark measures associated with general two-variable rational inner functions (RIFs) on the bidisk, including those with singularities, and with general -variable ration…
Alternative proofs of Mandrekar's theorem
Linus Bergqvist
We present two alternative proofs of Mandrekar's theorem, which states that an invariant subspaces of the Hardy space on the bidisc is of Beurling type precisely when the shifts sa…
Rational inner functions and their Dirichlet type norms
Linus Bergqvist
We study membership of rational inner functions in Dirichlet-type spaces in polydisks. In particular, we prove a theorem relating such inclusions to integrability of partial…
