On unitary convex decompositions of vectors in a $J B^{*}$ -algebra

By exploiting his recent results, the author further investigates the extent to which variation in the coefficients of a unitary convex decomposition of a vector in a unital $J B^{*}$ -algebra permits the vector decomposable as convex combination of fewer unitaries; certain $C^{*}$ -algebra results due to M. Rørdam have been extended to the general setting of $J B^{*}$ -algebras.

Commutativity criterions in locally m-convex algebras.

Similarity:

In this paper we define the notions of semicommutativity and semicommutativity modulo a linear subspace. We prove some results regarding the semicommutativity or semicommutativity modulo a linear subspace of a sequentially complete m-convex algebra. We show how such results can be applied in order to obtain commutativity criterions for locally m-convex algebras.
