Abstract: Let ▫$H$▫ be an infinite-dimensional almost separable Hilbert space. We show that every local automorphism of ▫$mathscr{B}(H)$▫, the algebra of all bounded linear operators on a Hilbert space ▫$H$▫, is an automorphism.Keywords: mathematics, operator theory, automorphism, local automorphism, algebra of operators on a Hilbert spacePublished in DKUM: 07.06.2012; Views: 1533; Downloads: 104 Link to full text
