摘要:
Let N and M be two nontrivial nests on a real or complex Hilbert space H. Let algN and algM be two nest algebras. Suppose that phi is a linear bijective mapping from algN onto algM such that phi(AB+BA)=phi(A)phi(B)+phi(B)phi(A) for any A,B is an element of algN with AB=G , where G is an arbitrary but fixed operator in algN and phi(I)=I . Then phi is either an isomorphism or an anti-isomorphism.
