Exact Christoffel-Darboux expansions: A new, multidimensional, algebraic, eigenenergy bounding method

چکیده
Although the Christoffel-Darboux representation (CDR) plays an important role within theory of orthogonal polynomials, and many bosonic fermionic multidimensional Schrodinger equation systems can be transformed into a moment (MER), union two effective, algebraic, eigenenergy bounding method has been overlooked. This particular fusion representations, suitable for or systems, defines Orthonormal Polynomial Projection Quantization - Bounding Method (OPPQ-BM), as developed here. We use it to analyze several one dimensional including quadratic Zeeman effect strong-superstrong magnetic fields. For this problem, we match surpass excellent, but intricate, results Kravchenko et al (1996 Phys. Rev. A 54287) broad range fields, without need any truncations approximations.

We study the stability of convergence of the ChristoffelDarboux kernel, associated with a compactly supported measure, to the sine kernel, under perturbations of the Jacobi coefficients of the measure. We prove stability under variations of the boundary conditions and stability in a weak sense under ` and random ` diagonal perturbations. We also show that convergence to the sine kernel at x imp...
متن کاملPfaffians, Determinants, and Multivariable Christoffel–darboux Kernels
Abstract. We obtain expressions for the Christoffel–Darboux kernel of antisymmetric multivariable orthogonal polynomials as determinants and pfaffians. These kernels include correlation functions of orthogonal polynomial ensembles (with β = 2). In subsequent work, our results are applied in combinatorics (enumeration of marked shifted tableaux) and number theory (representation of integers as s...
متن کاملA Christoffel-Darboux formula for multiple orthogonal polynomials
Bleher and Kuijlaars recently showed that the eigenvalue correlations from matrix ensembles with external source can be expressed by means of a kernel built out of special multiple orthogonal polynomials. We derive a Christoffel-Darboux formula for this kernel for general multiple orthogonal polynomials. In addition, we show that the formula can be written in terms of the solution of the Rieman...
متن کاملThe Multidimensional Darboux Transformation
A generalization of the classical one-dimensional Darboux transformation to arbitrary n-dimensional oriented Riemannian manifolds is constructed using an intrinsic formulation based on the properties of twisted Hodge Laplacians. The classical two-dimensional Moutard transformation is also generalized to non-compact oriented Riemannian manifolds of dimension n ≥ 2. New examples of quasi-exactly ...
