Characterizing quasi-biweekly variability of the Asian monsoon anticyclone using potential vorticity and large-scale geopotential height field [PDF]
Atmospheric Chemistry and Physics, 2020 The spatial pattern of subseasonal variability of the Asian monsoon anticyclone is analyzed using long-term reanalysis data, focusing on the large-scale longitudinal movement.

On conjectures of Stenger in the theory of orthogonal polynomials
Journal of Inequalities and Applications, 2019 The conjectures in the title deal with the zeros xj $x_{j}$, j=1,2,…,n $j=1,2, \ldots ,n$, of an orthogonal polynomial of degree n>1 $n>1$ relative to a nonnegative weight function w on an interval [a,b] $[a,b]$ and with the respective elementary ...

Bijective proofs of skew Schur polynomial factorizations
, 2020 In a recent paper, Ayyer and Behrend present for a wide class of partitions factorizations of Schur polynomials with an even number of variables where half of the variables are the reciprocals of the others into symplectic and/or orthogonal group ...

Functions with Given Moments and Weight Functions for Orthogonal Polynomials
Rocky Mountain Journal of Mathematics, 1993 The author gives a constructive technique to find smooth functions with given moments. Earlier in the well-known moment problem it was guaranteed that for every sequence of complex numbers there is a function of bounded variation with the given moments in these numbers. The author shows how these weight functions are found.

Orthogonal Polynomials and Expansions for a Family of Weight Functions in Two Variables [PDF]
Constructive Approximation, 2012 Orthogonal polynomials for a family of weight functions on $[-1,1]^2$, $$ \CW_{\a,\b,\g}(x,y) = |x+y|^{2\a+1} |x-y|^{2\b+1} (1-x^2)^\g(1-y^2)^{\g}, $$ are studied and shown to be related to the Koornwinder polynomials defined on the region bounded by two lines and a parabola. In the case of $\g = \pm 1/2$, an explicit basis of orthogonal polynomials is

On the representation of functions by orthogonal series in weighted $L^p$ spaces [PDF]
Studia Mathematica, 1999 Summary: It is proved that if \(\{\varphi_n\}\) is a complete orthonormal system of bounded functions and \(\varepsilon>0\), then there exists a measurable set \(E\subset [0,1]\) with measure \(| E|>1-\varepsilon\), a measurable function \(\mu(x)\), \(0< \mu(x)\leq 1\), \(\mu(x)\equiv 1\) on \(E\), and a series of the form \(\sum^\infty_{k=1} c_k ...

Superharmonic Perturbations of a Gaussian Measure, Equilibrium Measures and Orthogonal Polynomials
, 2008 This work concerns superharmonic perturbations of a Gaussian measure given by a special class of positive weights in the complex plane of the form $w(z) = \exp(-|z|^2 + U^{\mu}(z))$, where $U^{\mu}(z)$ is the logarithmic potential of a compactly ...
