Functional determinants for radial operators

Klaus Kirsten Department of Mathematics, Baylor University, Waco, TX 76798 Abstract We derive simple new expressions, in various dimensions, for the functional determinant of a radially separable partial differential operator, thereby generalizing the one-dimensional result of Gel’fand and Yaglom to higher dimensions. We use the zeta function formalism, and the results agree with what one would...

Functional Determinants for General Self-adjoint Extensions of Laplace-type Operators Resulting from the Generalized Cone

In this article we consider the zeta regularized determinant of Laplace-type operators on the generalized cone. For arbitrary self-adjoint extensions of a matrix of singular ordinary differential operators modelled on the generalized cone, a closed expression for the determinant is given. The result involves a determinant of an endomorphism of a finite-dimensional vector space, the endomorphism...

On a functional equation for symmetric linear operators on $C^{*}$ algebras

‎Let $A$ be a $C^{*}$ algebra‎, ‎$T‎: ‎Arightarrow A$ be a linear map which satisfies the functional equation $T(x)T(y)=T^{2}(xy),;;T(x^{*})=T(x)^{*} $‎. ‎We prove that under each of the following conditions‎, ‎$T$ must be the trivial map $T(x)=lambda x$ for some $lambda in mathbb{R}$: ‎‎ ‎i) $A$ is a simple $C^{*}$-algebra‎. ‎ii) $A$ is unital with trivial center and has a faithful trace such ...

Determinants of Zeroth Order Operators

For compact Riemannian manifolds all of whose geodesics are closed (aka Zoll manifolds) one can define the determinant of a zeroth order pseudodifferential operator by mimicking Szego’s definition of this determinant for the operator: multiplication by a bounded function, on the Hilbert space of square-integrable functions on the circle. In this paper we prove that the non-local contribution to...

Radiographic Predictors for Short-term Functional Outcome after Radial Head Arthroplasty in Patients with Persistent Symptoms after Treatment for Radial Head

Background: Evaluation of the accurate position after radial head arthroplasty remains a challenge for surgeons.Standard radiographs are used to evaluate the position of the implant, however, results regarding radiographicdeficiencies on clinical outcome are not consistent. In this retrospective study our main aim was to determine if subtleradiographic deficiencies after radia...
