Fully probabilistic seismic source inversion – Part 1: Efficient parameterisation [PDF]
Solid Earth, 2014 Seismic source inversion is a non-linear problem in seismology where not just the earthquake parameters themselves but also estimates of their uncertainties are of great practical importance.

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 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 ...

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 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 ...
