A counterexample for H∞ approximable functions
Let be the unit disk. We show that for some relatively closed set F ⊂ there is a function f that can be uniformly approximated on F by functions of H∞, but such that f cannot be written as f = h + g, with h ∈ H∞ and g uniformly continuous on F. This answers a question of Stray. © 2000 American Mathe...
