Quasi-orthogonal Subalgebras of Matrix Algebras@
In the theory of quantum mechanics, an n-level system is described by the algebra Mn =Mn(C) of n× n complex matrices. The matrix algebra of a composite system consisting of an n-level and an m-level system is Mn ⊗Mm ≃ Mnm. A subalgebra of Mk corresponds to a subsystem of a k-level quantum system. In this paper, subalgebras contain the identity and are closed under the adjoint operation of matri...
متن کاملCHEBYSHEV SUBALGEBRAS OF JB-ALGEBRAS
In this note, we characterize Chebyshev subalgebras of unital JB-algebras. We exhibit that if B is Chebyshev subalgebra of a unital JB-algebra A, then either B is a trivial subalgebra of A or A= H R .l, where H is a Hilbert space
متن کاملREDEFINED FUZZY SUBALGEBRAS OF BCK/BCI-ALGEBRAS
Using the notion of anti fuzzy points and its besideness to and nonquasi-coincidence with a fuzzy set, new concepts in anti fuzzy subalgebras in BCK/BCI-algebras are introduced and their properties and relationships are investigated.
متن کاملNorming C∗-algebras by C∗-subalgebras
The purpose of this paper is to introduce and explore a new concept for C∗-algebras: the notion of a norming C∗-subalgebra. The precise definition is given in the next section, but in general terms we have an inclusion A ⊆ B and we attempt to describe the norms of matrices over B by preand post-multiplying by rows and columns over A respectively, and calculating the norms of the resulting eleme...
متن کاملMaximal Nonfinitely Generated Subalgebras
We show that “every countable algebra with a nonfinitely generated subalgebra has a maximal nonfinitely generated subalgebra” is provably equivalent to ’1-CA0 over RCA0.
