β¦ Synopsis
In this paper, we prove that a bijective map Ο from A, a standard subalgebra of a nest algebra on a Hilbert space, onto an algebra that satisfies
where r is a fixed nonzero rational number, is additive.

Let A and B be two Jordan algebras. In this paper, we investigate the additivity of maps Ο from A onto B that are bijective and satisfy for all a, b β A. If A contains an idempotent which satisfies some conditions, then Ο is additive. This result generalizes all results about additivity of Jordan m
## Abstract Nest algebras provide examples of partial Jordan \*βtriples. If __A__ is a nest algebra and __A__~__s__~ = __A__ β© A\*, where __A__\* is the set of the adjoints of the operators lying in __A__, then (__A__, __A__~__s__~) forms a partial Jordan \*βtriple. Any weak\*βclosed ideal in the n
