The first difference between the pure algebraic and the
operator algebra context appeared in the definition of the partial skew group algebra, which is not automatically associative in the general situation.
Davidson, Fuller, and Kakariadis examine the semicrossed products of a semigroup action by *-endomorphisms on a C*-algebra, or more generally of an action on an arbitrary
operator algebra by completely contractive endomorphisms.
The
operator algebra analog [Alpha] # [Beta], which we call the join of [Alpha] and [Beta], is defined as follows.
Takesaki, Theory of
operator algebra I, Springer-Verlag, New York(1979).
The most prominent among them is freeness or free probability, which was introduced by Voiculescu to study questions in
operator algebra theory.
Originally published in Japanese for a Surveys in Geometry workshop held in Tokyo, Japan, in 1998, this translation offers an overview of
operator algebra theory.
Most of the book can be read with only a basic knowledge of functional analysis; however, some experience in the theory of
operator algebra is helpful.
Lie Algebras, Vertex
Operator Algebras, and Related Topics
The results will have a lasting impact on and connect further the theories of non-commutative geometry,
operator algebras, Lie theory, quantum group theory and partly quantum physics.
Vertex
operator algebras with central charge 1/2 and -68/7 .
He presents the theory of Krichever-Nobikov algebras, Lax
operator algebras, their interaction, elements of their representation theory, relations to moduli spaces of Riemann surface and holomorphic vector bundles of them and to Lax integrable systems and conformal field theory.
Other topics of the 17 papers include nonself-adjoint
operator algebras for dynamical systems, noncommutative geometry as a functor, examples of mases in C*-algebras, simple group graded rings, and classifying monotone complete algebras of operators.
