Christoffel–Darboux Kernels in Several Real Variables

چکیده
Abstract The Christoffel–Darboux kernels for orthogonal polynomials in several real variables are investigated within the context of three-term relation reformulated this purpose. As suggestive examples orthogonality, we propose to discuss two simple algebraic cases: unit circle and Bernoulli lemniscate.

Q Spaces of Several Real Variables
For 2 (?1; 1), let Q (R n) be the space of all measurable functions with supp`(I)] 2?n Z I Z I jf(x) ? f(y)j 2 jx ? yj n+2 dx dy < 1; where the supremum is taken over all cubes I with the edge length`(I) and the edges parellel to the coordinate axes in R n. If 2 (?1; 0), then Q (R n) = BMO(R n), and if 2 1; 1), then Q (R n) = fconstantsg. In the present paper, we discuss the case 2 0; 1). These...

متن کاملFourier Series in Several Variables
0. Preface. This article is a survey of certain aspects of the theory of multiple Fourier and trigonometric series. I t is by no means meant to be a complete survey; for example, it is practically disjoint with the material covered on the subject in Zygmund's book [38, Chapter 17.]. There are eight sections to this survey. §1 is the introduction. §2, §3, and §4 are expository in the sense that ...
