Abstract
In the Summer Seminar at Tateyama in Japan of Several Complex Variables, 18th July 1994, Professor T. Ohsawa posed the following problem in his talk [11].
PROBLEM (Ohsawa) Let Ω be a bounded pseudoconvex domain in C n and H be a one-codimensional complex linear subspace of C n. For any bounded holomorphic function g on Ω∩H, does there exist a bounded holomorphic function f on Ω such that the restriction f|Ω∩H of f to Ω∩H coincides with g on Ω∩H?
We give a counterexample for Ohsawa's Problem on bounded holomorphic extensions from hyperplanes to unbounded pseudoconvex domains.
