In this paper, we characterize rank-1 preserving linear maps between nest algebras acting on real or complex Banach spaces. As applications, we show that every weakly continuous and surjective local automorphism (or, anti-automorphism) on a nest algebra with an additional property is either an autom

Let L be a J-subspace lattice on a real or complex Banach space X with dim X > 2 and AlgL be the associated J-subspace lattice algebra. Let ฮด : AlgL โ AlgL be an additive map. It is shown that, if ฮด is derivable at zero point, i.e., ฮด(AB) = ฮด(A)B + Aฮด(B) whenever AB = 0, then ฮด(A) = ฯ (A) + ฮปA, โA,
Let A be a unital matrix algebra, ฯ : A โ M n (C) a unital linear mapping and B the algebra generated by ฯ(A). The mapping ฯ is a homomorphism modulo the Jacobson radical in B if and only if for k = dim(B)dim(ฯ(A)) + 3 the mapping ฯ โ id : A โ M k (C) โ B โ M k (C) preserves invertibility. This resu
