On the function Tr exp ( A + itB ) 1

چکیده
We prove, for two free semicircularly distributed selfadjoint elements a and b in a type II1 von Neumann algebra with faithful trace , that the function t 2 R 7! (exp(a + itb)) is positive de nite. This shows that the BessisMoussa-Vilani conjecture holds for large random matrices in an asymptotic sense.

Perturbation of Wigner matrices and a conjecture
Let H0 be an arbitrary self-adjoint n × n matrix and H(n) be an n × n (random) Wigner matrix. We show that t 7→ Tr exp(H(n)−itH0) is positive definite in the average. This partially answers a long-standing conjecture. On the basis of asymptotic freeness our result implies that t 7→ τ(exp(a − itb)) is positive definite whenever the noncommutative random variables a and b are in free relation, wi...
متن کاملLateral Knee Pain after Outside-in Anatomic Double-Bundle Anterior Cruciate Ligament Reconstruction Using the TightRope RT.
The anterior cruciate ligament (ACL) TightRope RT (TR) was recently introduced as a novel cortical suspension device for ACL reconstruction. It has an adjustable graft loop that gives the surgeon some advantages during ACL reconstruction. We report three patients who required removal of the TR after an outside-in anatomical ACL reconstruction because of lateral knee pain. We assumed that the kn...
متن کاملAPPLICATION OF EXP-FUNCTION METHOD TO THE (2+1)-DIMENSIONAL CALOGERO BOGOYAVLANSKII SCHIFF EQUATION
In this paper, the Exp-function method, with the aid of a symbolic computation system such as Maple, is applied to the (2+1) -dimensional Calogero Bogoyavlanskii Schiff equation. Exact and explicit generalized solitary solutions are obtained in more general forms. The free parameters can be determined by initial or boundary conditions. The method is straightforward and concise, and its applicat...
متن کاملExp-Kumaraswamy Distributions: Some Properties and Applications
In this paper, we propose and study exp-kumaraswamy distribution. Some of its properties are derived, including the density function, hazard rate function, quantile function, moments, skewness and kurtosis. Adata set isused to illustrate an application of the proposed distribution. Also, we obtain a new distribution by transformation onexp-kumaraswamy distribution. New distribution is an...
متن کاملComparison of respiratory parameters and plasma cytokine levels between treatment with Salmeterol/fluticasone and ipratropium/terbutaline/budesonide in mechanically ventilated COPD patients.
BACKGROUND It is unknown whether the bronchodilation and anti-inflammatory effects of inhaled salmeterol and fluticasone (SF) are better than those of traditionally inhaled ipratropium, terbutaline and budesonide (ITB) in mechanically ventilated patients with chronic obstructive pulmonary disease (COPD). METHODS Nineteen stable COPD patients with respiratory failure were randomly enrolled int...
