Hermitian smoothing
WitrynaUsing the smoothing property for the corresponding parabolic flow, a weak solution is proved to be smooth if the background Hermitian metric satisfies a compatibility condition. The Chern-Ricci flow is an evolution equation of Hermitian metrics on a complex manifold by their Chern-Ricci form. The existence and uniqueness for the … Witrynavariety Xw in a Hermitian symmetric space, any irreducible subvariety X with the homology class [X]=r[Xw], r ∈ Z, is again a Schubert variety of type w, unless Xw is a non-maximal linear space. In particular, any local deformation of such a smooth Schubert variety in Hermitian symmetric space G/P is obtained by the action of the …

WitrynaA smoothing inequality for complex measures that quantitatively relates the uniform Kolmogorov-like distance to the concentration of logarithmic potentials is shown. Combining it with results from Local Circular Laws, we apply it to prove nearly optimal rate of convergence to the Circular Law in Kolmogorov distance. WitrynaThey also suffer from speckle noise which reduces the signal-to-noise ratio. Smoothing techniques have been proposed in the literature aiming at preserving different features and, analogously, projections from the cone of Hermitian positive matrices to different color representation spaces are used for enhancing certain characteristics.
A Hermitian metric on a complex vector bundle E over a smooth manifold M is a smoothly varying positive-definite Hermitian form on each fiber. Such a metric can be viewed as a smooth global section h of the vector bundle $${\displaystyle (E\otimes {\bar {E}})^{*}}$$ such that for every point p in M, A … Zobacz więcej In mathematics, and more specifically in differential geometry, a Hermitian manifold is the complex analogue of a Riemannian manifold. More precisely, a Hermitian manifold is a complex manifold with a smoothly varying Zobacz więcej Every (almost) complex manifold admits a Hermitian metric.

WitrynaA new Hermite cubic smoothing scheme for the computational description of contact surfaces is outlined. Attention is focused on the two dimensional case, although the scheme is designed to be extendible to three dimensions. A numerical result illustrates the utility of the proposed scheme.
WitrynaSolve the square linear system Ax = b of size n using QMR. QMR is based on the Lanczos biorthogonalization process and requires two initial vectors b and c. The relation bᴴc ≠ 0 must be satisfied and by default c = b. When A is Hermitian and b = c, QMR is equivalent to MINRES. reaction to song everybody hurtsWitrynaWe analyze the dispersive properties of a Dirac system perturbed with a magnetic field. We prove a general virial identity; as applications, we obtain smoothing and endpoint Strichartz estimates which are optimal from the decay point of view. We also prove a Hardy-type inequality for the perturbed Dirac operator. reaction to song the boxerWitryna694 Bent ØRSTED & Jorge VARGAS to attack this problem is to consider geometric realizations of the represen-tation in question.
