C Star Algebra
C Star Algebra. A → a, b ↦ a b + λ b is the multiplication operator. Of course, if a is a normed algebra, then the norm induces a metric on a which similarly weak star topology on a∗ is generated by the sets.
Algebra n nmatrices, m n:= m n(c), with the usual matrix operations from linear algebra. A is closed under the operation of taking adjoints of operators. Of the algebra of bounded operators on h h that is closed in the norm.
However, It Would Be Easier To Work With Specific Constructions Of The Multiplier Algebra, That In Fact Give Rise To The Name.

A is closed under the operation taking adjoints of operators. The opposite does not hold as we shall see in section 5. A![0;1) such that n1:(de niteness) kak= 0 if and only if a= 0,
