本文刻画了两个套代数T(N)和T(M)之间的线性映射<$,满足<$(AB − BA)=<$(A)<$(B)− <$(B)<$(A),对所有A,B ∈ T(N)。特别地,它表明,这样的同构只存在,如果N是类似于M或M。
Abstract In this paper we characterize linear maps ϕ between two nest algebras T ( N ) and T ( M ) which satisfy the property that ϕ ( AB − BA )= ϕ ( A ) ϕ ( B )− ϕ ( B ) ϕ ( A ) for all A , B ∈ T ( N ). In particular, it is shown that such isomorphisms only exist if N is similar to M or M ⊥ .
