the strict topology. The double centralizer concept is of interest because it in-cludes many important examples. For example, if, A is a commutative C*-alge-bra, A may be regarded as the algebra C0(S) (S — the maximal ideal space of A) of continuous functions on S vanishing at infinity., …

Guide to Electric Bike Motors | Rad Power Bikes

Located in the rear hub of the wheel, the motor utilizes a system of magnets to propel the bike. One of the biggest benefits of the magnetic system is that it can offer a regenerative braking feature.. That means when you brake, it will convert some of the momentum of the bike into electricity to charge the battery.

An important fact in the theory of central simple algebras is the double centralizer theorem, which says: if, \$k\$ is a field, \$A\$ is a \$k\$-algebra,, \$V\$, is a faithful semisimple \$A\$-algebra,, then \$C(C(A)) = A\$,, where \$C(A)\$ is the centralizer of \$A\$ in, \$End_k(V)\$. Taking the centralizer is an inclusion-reversing operation.

Character theory - Wikipedia

In mathematics, more specifically in group theory, the character of a group representation is a function on the group that associates to each group element the trace of the corresponding matrix. The character carries the essential information about the representation in a more condensed form. Georg Frobenius initially developed representation theory of finite groups entirely based on the ...

For ,example,, when the baby monster was discovered, it had a ,double, cover, which was a potential ,centralizer, of an involution in a larger simple group, which turned out to be the monster. The monster happens to have no ,double, cover so the process stopped there, but without checking every ﬁnite simple

CUBIC DOUBLE CENTRALIZERS AND CUBIC MULTIPLIERS

A is said to be left ,centralizer, on A if L(ab) = L(a)b for all a;b 2 A. Similarly, a linear mapping R: A ! A that R(ab) = aR(b) for all a;b 2 A is called right ,centralizer, on A. A double ,centralizer, on A is a pair (L;R), where L is a left ,centralizer,, R is a right ,centralizer, and aL(b) = R(a)b for all a;b 2 A. For ,example,, (Lc;Rc) is a double ,centralizer,, where Lc(a) := ca

If both ϕ and ψ are surjective, we call that the triple (A,B,M)satisﬁes the double ,centralizer, property. Such double ,centralizer, property plays a central role in many parts of algebraic Lie theory. For ,example,, let R=C, the complex numbers ﬁeld; A=CGLm(C), the group algebra (over C) for general linear group; B=CSn, the group algebra (over C)forthe
