Abstract

The development in countable inductive limits of weighted Banach spaces of continuous functions and their projective description had been surveyed before.  This case can nowadays be considered as settled completely ; all important properties are characterized, even for (LF)-spaces.  The present survey, however, is devoted to a description of the “state of the art” in countable inductive limits H (G) and oH(G) of weighted Banach spaces of holomorphic functions and their projective description. Here many problems have remained open.  It is known for quite a while that H(G) = H(G) holds topologically whenever the inductive limit H(G) is a (semi-) Montel space.  Counterexamples to projective description for O-growth conditions were given only during the last years, by Bonet and his co-authors Taskinen, Melikhov, Vogt, respectively.  But it is not known if there are any counterexamples for oH(G) ; i.e., in the case of o-growth conditions.  Among other things, we discuss the analogy between Köthe sequence spaces and spaces of holomorphic functions, the use of the predual of H(G), and the biduality of oH(G) and H(G).  One section is devoted to vector valued projective description in a good situation and its connection to an operator representation. Interesting new problems arise here.  Finally, the article concludes with some remarks on the proper (Lf)-case, in which, despite various efforts, no general positive projective description result is known for spaces of holomorphic functions.
