The algebra of all bounded real- or complex-valued functions defined on some set (with pointwise multiplication and the supremum norm) is a unital Banach algebra.
The algebra of all bounded continuous real- or complex-valued functions on some locally compact space (again with pointwise operations and supremum norm) is a Banach algebra.

Soon later Fedosov gave his geometric construction of star products on symplectic manifolds in 1985 which was unfortunately unnoticed till the early nineties, see his book for a detailed description [fedosov:1996a].
Roughly, a strict deformation quantization of a (Poisson) C* algebra A is the data of a continuous field of C* algebras over an interval containing zero.
This algebraic GNS construction is also the starting point for a general representation theory of the deformed algebras.

-algebra is *-isomorphic to a closed subalgebra of such an operator algebra for a suitable Hilbert space H; this is the content of the Gelfand-Naimark theorem[?].
-algebra is the algebra C(X) of all complex-valued continuous functions defined on a compact Hausdorff space X.
Here the norm of a function is the supremum of its absolute value, and the star operation is complex conjugation.

 California Standardized Testing And Reporting (STAR) Program
Students in grades 9 and 10 who completed Algebra II or 3rd Year Integrated Mathematics during a previous school year and grade 11 students who completed one of these two courses anytime prior to the beginning of testing were required to take the California High School Summative Mathematics Standards Test.
In addition to using the blueprints to select the most appropriate test to administer during spring 2003, teachers of integrated science courses were asked to begin aligning their course content with one or more of the test blueprints as appropriate.
The CAT/6 surveys are shorter than the Stanford 9 and reduce the testing time for the norm-referenced portion of the STAR program.

In an earlier paper we showed that the set of "two-restricted" tilting complexes for the Brauer star algebra is in one-to-one correspondence with the set of brauer trees with an additional structure called a pointing, which determines the folding of the complex.
Here we show that the subgroup of self-equivalences of the Brauer star algebra obtained by going out with one pointing and returning by another is generated by e generators which satisfy the braid relations for the Euclidean diagram which is a cycle.

STAR augmentation scores for mathematics are reported for all students for grades 2 through 7 and grade 11.
Mathematics scores for grades 8, 9, and 10 are reported by mathematics course as specified in California's content standards: for grade 8, algebra I or 1st year integrated mathematics; grade 9, geometry or 2nd year integrated mathematics; and grade 10, algebra II or 3rd year integrated mathematics.
Students taking the algebra I STAR augmentation at grade 9, however, would not take any Stanford 9 items identified as contributing to the total score because the Stanford 9 items selected for use at grade 9 were chosen as foundation skills for geometry, not for algebra.

 Deformation Quantization
Deformation quantization is a quantization scheme which is applied mainly for systems of classical mechanics, where one concentrates on the algebra of observables: classically the observables are the smooth complex-valued functions on the phase space which is modeled by a symplectic or Poisson manifold.
They are an associative and commutative algebra with respect to the pointwise product and from the symplectic or Poisson structure on the manifold they inherit a Poisson bracket which makes the classical observables into a Poisson algebra.
While the structure of the observable algebra is quite well understood a physically reasonable concept for the states seemed to be missing.

ABSTRACT: The extension of the noncommutative u$_{\star}(N)$ Lie algebra to noncommutative orthogonal and symplectic Lie algebras is studied.
We give explicit fundamental matrix representations of these algebras, through which the formulation for the corresponding noncommutative gauge field theories are obtained.

In this paper we show that in the presence of an antisymmetric tensor B background, Witten's star algebra for open string fields persists to possess the structure of a direct product of commuting Moyal pairs.
The interplay between the noncommutativity due to three-string overlap and that due to the B background is our main concern.
We have also demonstrated the large-B contraction of the star algebra, with one of the discrete Moyal pairs dropping out and with the other giving rise to the center-of-mass noncommutative function algebra.
