Preferred Abstract (Original): 

The Hardy-Orlicz space is the space of all analytic functions on the open unit disk such that the subharmonic function has a harmonic majorant on where is a modulus function. is the space of all such that has a quasi-bounded harmonic majorant on . Under certain constraints on we show that multiplicative linear functionals on are exactly point evaluation and ring homomorphisms of are just composition operators.Examples of such are and .This generalizes the special case where is the well known Smirnov class.

Preferred Abstract (Original): 

The Hardy-Orlicz space is the space of all analytic functions on the open unit disk such that the subharmonic function has a harmonic majorant on where is a modulus function. is the subspace of consisting of all such that has a quasi-bounded harmonic majorant on . If , then is the Hardy space and if ,then is the Nevanlinna class and is the Smirnov class .In this paper we generalize some of N. Yanagihara's and A. Hartmann's and others interpolation results from and to and .For that purpose we generalize a canonical factorization theorem to functions in or and introduce an F-space of complex sequences.
