The product of a weak Asplund space and a one-dimensional space is a weak Asplund space: over 45 years of open problem solved
Shaoqiang Shang
In this paper, authors prove that if is a weak Asplund space, then the space is a weak Asplund space. Thus the author definitely answered an open problem raised by…
