Abstract Let ϕ be a surjective Jordan homomorphism from a nest algebra Alg N onto another nest algebra Alg M . It is showed that ϕ is a homomorphism, or ϕ is an anti-homomorphism, or ϕ ( N ) = { 0 , I } . Furthermore, if Alg N is of infinite multiplicity, then ϕ is either a homomorphism or an anti-homomorphism.

嵌套代数的 Jordan 表象

摘要 令 ϕ 是从一个嵌套代数 Alg N 到另一个嵌套代数 Alg M 的满射 Jordan 同态。证明 ϕ 是一个同态,或者 ϕ 是一个反同态,或者 ϕ ( N ) = { 0 , I } 。此外,如果 Alg N 具有无限重数,则 ϕ 要么是同态,要么是反同态。
