Some quasinilpotent generators of the hyperfinite II1 factor
For each sequence {cn}n in l1(N) we define an operator A in the hyperfinite II1factor R. We prove that these operators are quasinilpotent and they generate the whole hyperfinite II1 factor. We provide enough evidence to suggest that these operators are interesting for the hyperinvariant subspace problem.
