Abstract. Let A(R) and E(R) denote respectively the ring of analytic and real entire functions in one variable. It is shown that if m is a maximal ideal of A(R), then A(R)/m is isomorphic either to the reals or a real closed field that is an η 1 -set, while if m is a maximal ideal of E(R), then E(R)/m is isomorphic to one of the latter two fields or to the field of complex numbers. Moreover, we study the residue class rings of prime ideals of these rings and their Krull dimensions. Use is made of a classical characterization of algebraically closed fields due to E. Steinitz and techniques described in L. Gillman and M. Jerison's book on rings of continuous functions.

“…The following wellknown lemma will be useful later: For Λί a finitely generated R-module, we denote by μ(R,M) the minimum number of generators required for Λf over R. matrix (α iy ) in which α« divides a i+UM9 R is an elementary divisor ring. It has recently been shown [7] that a ring is an elementary divisor ring if and only if every finitely presented module is a direct sum of cyclics. We will see later, in (3.4), that the conditions of (1.5) also have a matrix-theoretic formulation.…”
