N. R. Nandakumar

International Journal of Mathematics and Mathematical Sciences, 1990, vol. 13, 1-4

Abstract:

It is shown that a ring homomorphism on H ( G ) , the algebra of analytic functions on a regular region G in the complex plane, is either linear or conjugate linear provided that the ring homomorphism takes the identity function into a nonconstant function.
