Abstract

Two topologies of a Hilbert space l 2 is considered in this work. To wit normed
vector space, which is its natural topology and weak topology. Among other properties we showed that the closed unit ball S is not compact when l 2∗ is given its topology as a Banach space. On the other hand S is compact when l 2∗ is given its weak topology.
