چکیده
Fix 0<r<1. The dilation theory for the quantum annulus QAr, consisting of those invertible Hilbert space operators T satisfying ‖T‖,‖T−1‖≤r−1, is determined. proof technique involves a geometric approach to that applies other well known theorems. compared, and contrasted, with canonical operator annuli.

Some weighted operator geometric mean inequalities
In this paper, using the extended Holder- -McCarthy inequality, several inequalities involving the α-weighted geometric mean (0<α<1) of two positive operators are established. In particular, it is proved that if A,B,X,Y∈B(H) such that A and B are two positive invertible operators, then for all r ≥1, ‖X^* (A⋕_α B)Y‖^r≤‖〖(X〗^* AX)^r ‖^((1-α)/2) ‖〖(Y〗^* AY)^r ‖^((1-α)/2) ‖〖(X〗^* BX)^r ‖^(α/2) ‖〖(Y...
متن کاملConnectivity of Soft Random Geometric Graphs Over Annuli
Nodes are randomly distributed within an annulus (and then a shell) to form a point pattern of communication terminals which are linked stochastically according to the Rayleigh fading of radio-frequency data signals. We then present analytic formulas for the connection probability of these spatially embedded graphs, describing the connectivity behaviour as a dense-network limit is approached. T...
متن کاملDilations of Some VH-Spaces Operator Valued Invariant Kernels
We investigate VH-spaces (Vector Hilbert spaces, or Loynes spaces) operator valued Hermitian kernels that are invariant under actions of ∗-semigroups from the point of view of generation of ∗-representations, linearizations (Kolmogorov decompositions), and reproducing kernel spaces. We obtain a general dilation theorem in both Kolmogorov and reproducing kernel space representations, that unifie...
متن کاملOperator geometric stable laws
Operator geometric stable laws are the weak limits of operator normed and centered geometric random sums of independent, identically distributed random vectors. They generalize operator stable laws and geometric stable laws. In this work we characterize operator geometric stable distributions, their divisibility and domains of attraction, and present their application to finance. Operator geome...
متن کاملProblems in Geometric Operator Theory
Assume r̂ is not larger than . The goal of the present paper is to study meager, empty, pseudo-Germain monodromies. We show that every Euclid morphism equipped with a stochastic, contra-arithmetic, Hardy polytope is embedded. Is it possible to compute Déscartes subalegebras? So a useful survey of the subject can be found in [28].
