Webalgebras. The space X1 has a Calkin algebra isometrically isomorphic to the Banach algebra ℓ1(N0) with convolution product, which is semisimple [4, theorem 4.6.9(i)]. (xiii) … WebThe Calkin algebra provides both a natural context and a powerful tool for studying compact perturbations of operators on a Hilbert space. The original motivation for the problem solved inTheorem 1comes from a classi cation problem for normal operators.
