The invariant subspace problem on Hilbert space

The logarithm function log(x.y) = log(x) + log(y) so it is a group homomorphism R+->R. The exponential function e^(x+y) = e^x . e^y so it too is a homomorphism R->R+ Another note: Formalizing intuition (of existence of natural isomorphism between vector space V and its 'dual dual') is a motivation for the development of category theory.
