Invariant elements in the dual Steenrod algebra
In this paper, we investigate the invariant elements of the dual mod $p$ Steenrod subalgebra ${mathcal{A}_p}^*$ under the conjugation map $chi$ and give bounds on the dimensions of $(chi-1)({mathcal{A}_p}^*)_d$, where $({mathcal{A}_p}^*)_d$ is the dimension of ${mathcal{A}_p}^*$ in degree $d$.
متن کاملC*-Algebra numerical range of quadratic elements
It is shown that the result of Tso-Wu on the elliptical shape of the numerical range of quadratic operators holds also for the C*-algebra numerical range.
متن کاملThe Multiplier Algebra of a Nuclear Quasidiagonal C-algebra
We give the nuclear analogue of Dadarlat’s characterization of exact quasidiagonal C∗-algebras. Specifically, we prove the following: Theorem 0.1. Let A be a unital separable simple C∗-algebra. Then the following conditions are equivalent: i) A is nuclear and quasidiagonal. ii) A has the stabilization principle. iii) If π : A → M(A ⊗ K) is a unital, purely large ∗-homomorphism, then the image π...
متن کاملSearching for an algebra on CSP solutions
The Constraint Satisfaction Problem (CSP) is a problem of computing a homomorphism R → Γ between two relational structures, where R is defined over a domain V and Γ is defined over a domain D. In fixed template CSPs, denoted CSP(Γ), the right side structure Γ is fixed and the left side structure R is unconstrained. In the last 2 decades it was impressively revealed that reasons that make fixed ...
متن کاملOn an AF -algebra of the Hecke eigenform
To every cusp form f of weight two an AF -algebra Af (an operator algebra) is assigned. The properties of Af are studied in the case when f is a Hecke eigenform. A conjecture on the K-theory of the Bost-Connes algebra is formulated.
