Isometric Gelfand transforms of complete Nevanlinna-Pick spaces (2502.06240v1)
Published 10 Feb 2025 in math.FA, math.CV, and math.OA
Abstract: We show that any complete Nevanlinna-Pick space whose multiplier algebra has isometric Gelfand transform (or commutative C*-envelope) is essentially the Hardy space on the open unit disk.
