The classification problem for operator algebraic varieties and their multiplier algebras
Michael Hartz, Martino Lupini
We study from the perspective of Borel complexity theory the classification problem for multiplier algebras associated with operator algebraic varieties. These algebras are precise…

Von Neumann's inequality for commuting weighted shifts
Michael Hartz
We show that every multivariable contractive weighted shift dilates to a tuple of commuting unitaries, and hence satisfies von Neumann's inequality. This answers a question of Lubi…

On the isomorphism problem for multiplier algebras of Nevanlinna-Pick spaces
Michael Hartz
We continue the investigation of the isomorphism problem for multiplier algebras of reproducing kernel Hilbert spaces with the complete Nevanlinna-Pick property. In contrast to pre…
