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.
We compute some large-scale properties of the uniform spanning tree process on Z 2. In particular we compute certain crossing probabilities for rectangles and annuli.
BACKGROUND Proponents of flexible annuloplasty rings have hypothesized that such devices maintain annular dynamics. This hypothesis is based on the supposition that annular motion is relatively normal in patients undergoing mitral valve repair. We hypothesized that mitral annular dynamics are impaired in ischemic mitral regurgitation and myxomatous mitral regurgitation. METHODS AND RESULTS A ...
The physiological blind spot, corresponding to the optic disk in the retina, is a relatively large (6 × 8°) area in the visual field that receives no retinal input. However, we rarely notice the existence of it in daily life. This is because the blind spot fills in with the brightness, color, texture, and motion of the surround. The study of filling-in enables us to better understand the creati...
We study the zeros of cross-product Bessel functions and obtain their approximations, based on which we reduce eigenvalue counting problem for Dirichlet Laplacian associated with a planar annulus to lattice point special domain in R 2 . Unlike other problems, one arisen naturally here has interesting features that points under consideration are translated by various amounts curvature boundary i...
