Order unit property of a positive element in a -algebra is defined. It is proved that precisely projections satisfy this order theoretic property. This way, unital hereditary C*-subalgebras of a -algebra are characterized.doi:10.1007/BF02829679Anil K. Karn...
This constructs the canonical approximate unit in an arbitrary C⋆-algebra. This approximate unit is the filter corresponding to the basis of sections {x | a ≤ x} ∩ closedBall 0 1, where 0 ≤ a and ‖...
Automorphisms and ideals of the Weyl algebra Let $A_1$ be the (first) Weyl algebra, and let G be its automorphism group. We study the natural action of G on the space of isomorphism classes of right i... Y Berest,G Wilson - 《Mathematische Annalen》 被引量: 149发表: 2000年 ...
A method of computing in which different parts of a task are distributed between two or more similar central processing units, allowing the computer to complete operations more quickly and to handle larger, more complex procedures.

(n, rq) = 1 and q is the multiplicative order of r modulo n. In this paper, we address the problem of computing the Wedderburn decomposition of the group algebra Fqk (Cn r Cq) modulo its Jacobson radical. As a consequence, the structure of the unit group of Fqk (Cp r Cq) is ...
I think we can just use the same idea how we resolvefont-size: 1ex: when a font-relative length unit is used in a font-related property, it refers to the the parent element's font. Sorry, something went wrong. Copy link Contributor ...
