Abstract
The theory of commuting operators with finite-dimensional imaginary parts which has been developed during the last decade yielded fruitful connections with algebraic geometry. Let A = (A 1,..., A n ) be an n-tuple of commuting bounded operators with finite non-Hermitian rank in a Hilbert space H and let A* = (A *1 ,..., A * n ) be the adjoint n-tuple.
