Sorting Operators for Finite Sequences
(Def. 1)(i) If len f = 0, then maxp f = 0, and (ii) if len f > 0, then maxp f ∈ dom f and for every natural number i and for all real numbers r1, r2 such that i∈ dom f and r1 = f (i) and r2 = f (maxp f ) holds r1 ≤ r2 and for every natural number j such that j ∈ dom f and f ( j) = f (maxp f ) holds maxp f ≤ j. Let f be a finite sequence of elements of R. The functor minp f yields a natural numb...
متن کاملOn spectral approximation, Følner sequences and crossed products
In this article we review first some of the possibilities in which the notions of Følner sequences and quasidiagonality have been applied to spectral approximation problems. We construct then a canonical Følner sequence for the crossed product of a concrete C∗-algebra and a discrete amenable group. We apply our results to the rotation algebra (which contains interesting operators like almost Ma...
متن کاملSubspace-diskcyclic sequences of linear operators
A sequence ${T_n}_{n=1}^{infty}$ of bounded linear operators on a separable infinite dimensional Hilbert space $mathcal{H}$ is called subspace-diskcyclic with respect to the closed subspace $Msubseteq mathcal{H},$ if there exists a vector $xin mathcal{H}$ such that the disk-scaled orbit ${alpha T_n x: nin mathbb{N}, alpha inmathbb{C}, | alpha | leq 1}cap M$ is dense in $M$. The goal of t...
متن کاملThe Jacobsthal Sequences in Finite Groups
Abstract In this paper, we study the generalized order- Jacobsthal sequences modulo for and the generalized order-k Jacobsthal-Padovan sequence modulo for . Also, we define the generalized order-k Jacobsthal orbit of a k-generator group for and the generalized order-k Jacobsthal-Padovan orbit a k-generator group for . Furthermore, we obtain the lengths of the periods of the generalized order-3 ...
متن کاملFinite Operators
A bounded linear operator A on a Hilbert space H is called finite if \\AX-XA -l|| èl for each XEB(H). The class of finite operators is uniformly closed, contains every normal operator, every operator with a compact direct summand, and the entire C*-algebra generated by each of its members. These results imply that the set of operators with a finite dimensional reducing subspace is not uniformly...
