Skew exactness perturbation
Robin Harte and David Larson The first author was partially supported by Enterprise Ireland grant number IC/2001/027 Abstract We offer a perturbation theory for finite ascent and descent properties of bounded operators. There are various degrees of “skew exactness” ([10];[7] (10.9.0.1), (10.9.0.2)) between compatible pairs of operators, bounded and linear between normed spaces: 1. Definition Su...
متن کاملPutnam-fuglede Theorem and the Range-kernel Orthogonality of Derivations
Let (H) denote the algebra of operators on a Hilbert space H into itself. Let d= δ or , where δAB : (H)→ (H) is the generalized derivation δAB(S)=AS−SB and AB : (H) → (H) is the elementary operator AB(S) = ASB−S. Given A,B,S ∈ (H), we say that the pair (A,B) has the property PF(d(S)) if dAB(S) = 0 implies dA∗B∗(S) = 0. This paper characterizes operators A,B, and S for which the pair (A,B) has p...
متن کاملDual Skew Products, Genericity of the Exactness Property and Finance
Let us consider two homeomorphims S0, S1 of the interval I = [0, 1] onto itself. They determine the random walk on I as follows: x goes to S0(x) with probability p and x goes to S1(x) with probability q. Random walks on I may be realized as transformations of a larger space. Let Ω be the space {0, 1}N , N = {0, 1, 2, . . .}, with the (p, q)-measure μp on (Ω,B), where B is the Borel product σ-al...
متن کاملOn parameter orthogonality in symmetric and skew models
Orthogonal and partly orthogonal reparametrisations are provided for certain wide and important families of univariate continuous distributions. First, the orthogonality of parameters in location-scale symmetric families is extended to symmetric distributions involving a third parameter. This sets the scene for consideration of the four-parameter situation in which skewness is also allowed. It ...
متن کاملNumerical Range and Orthogonality in Normed Spaces
Introducing the concept of the normalized duality mapping on normed linear space and normed algebra, we extend the usual definitions of the numerical range from one operator to two operators. In this note we study the convexity of these types of numerical ranges in normed algebras and linear spaces. We establish some Birkhoff-James orthogonality results in terms of the algebra numerical range V...
