Abstract

A committee space is a Hilbert space of power series, perhaps in several or noncommuting variables, such that zαzβzα+β.\|z^\alpha\|\|z^\beta\| \geq \|z^{\alpha+\beta}\|. Such a space satisfies the true column-row property when ever the map transposing a column multiplier to a row multiplier is contractive. We describe a model for random multipliers and show that such random multipliers satisfy the true column-row property. We also show that the column-row property holds asymptotically for large random Nevanlinna-Pick interpolation problems where the nodes are chosen identically and independently. These results suggest that finding a violation of the true column-row property for the Drury-Arveson space via na\"ive random search is unlikely.
