An anti-open mapping theorem for Fréchet spaces

Steven F. Bellenot

Vol. 83 (1979), No. 2, 325–331
Abstract

It is well-known that completeness is necessary for the usual open mapping theorem for Fréchet spaces. In contrast, it is shown that, with the obvious exception of ω, each infinite-dimensional Fréchet space has another distinct complete topology with the same continuous dual.
