Abstract:  A Qalgebra can be represented as an operator algebra on an infinite dimensional Hilbert space. However we don't know whether a finite ndimensional Qalgebra can be represented on a Hilbert space of dimension n except n = 1, 2. It is known that a two dimensional Qalgebra is just a two dimensional commutative operator algebra on a two dimensional Hilbert space. In this paper we study a finite ndimensional semisimple Qalgebra on a finite ndimensional Hilbert space. In particular we describe a three dimensional Qalgebra of the disc algebra on a three dimensional Hilbert space. Our studies are related to the Pick interpolation problem for a uniform algebra.
