Abstract
Let Ξ΄ be a Lie triple derivation from a nest algebra π into an πβbimodule β³οΈ. We show that if β³οΈ is a weak* closed operator algebra containing π then there are an element S β β³οΈ and a linear functional f on π such that Ξ΄ (A) = SA β AS + f (A)I for all A β π, and if β³οΈ is the ideal of all compact operators then there is a compact operator K such that Ξ΄ (A) = KA β AK for all A β π. As applications, Lie derivations and Jordan derivations on nest algebras are characterized. (Β© 2007 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)

In this paper we characterize linear maps . between two nest algebras T(N) and T(M) which satisfy the property that .(AB&BA)=. ## (A) .(B)&.(B) .(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 = .
Let R be a commutative algebra over a field k. We prove two related results on the simplicity of Lie algebras acting as derivations of R. If D is both a Lie subalgebra and R-submodule of Der k R such that R is D-simple and either char k = 2 or D is not cyclic as an R-module or D R = R, then we show
We define a restricted structure for Lie triple systems in the characteristic p ) 2 setting, akin to the restricted structure for Lie algebras, and initiate a study of a theory of restricted modules. In general, Lie triple systems have natural embeddings into certain canonical Lie algebras, the so-c
