Rank of truncated Hankel operators on model spaces

Year: 2025

Type: article

Abstract: We study the rank of truncated Hankel operators on model spaces K2u:= H2 ? uH2. Concrete rank formulas will be established for several classes of finite rank truncated Hankel operators. The rank formulas will be derived seperately depending on whether the model space K2u is finite-dimensional, or, infinite-dimensional.
