Hyper invariant subspaces for compact perturbations of diagonal operators
The problem of the hyper-invariant subspace, for an operator T B(lp), T ≠λI, concerns the existence or not of a non-trivial closed subspace, which is invariant for all the operators which commute with T . This problem is still open for operators of the form D + K, D a diagonal operator and K a compact operator. In this talk, we will discuss the existence of non-trivial hyper-invariant subspaces for some operators of the form D + K.
