Invariant Subspaces "The Poor Lovers" is reprintedThis broad survey spans a wealth of studies on invariant subspaces, focusing on operators on separable Hilbert space. Largely self contained, it requires only a working knowledge of measure theory, complex analysis, and elementary functional analysis. Subjects include normal operators, analytic functions of operators, shift operators, examples of invariant subspace lattices, compact operators, and the existence of invariant and hyperinvariant
