Positivity of Riesz Functionals and Solutions of Quadratic and Quartic Moment Problems
Lawrence Fialkow, Jiawang Nie
We employ positivity of Riesz functionals to establish representing measures (or approximate representing measures) for truncated multivariate moment sequences. For a truncated mom…

An Arithmetic Metric
Diego Dominici
What is the distance between 11 (a prime number) and 12 (a highly composite number)? If your answer is 1, then ask yourself "is this reasonable?" In this work, we will introduce a…

Polynomial solutions of differential-difference equations
Diego Dominici, Kathy Driver, Kerstin Jordaan
We investigate the zeros of polynomial solutions to the differential-difference equation \[ P_{n+1}(x)=A_{n}(x)P_{n}^{\prime}(x)+B_{n}(x)P_{n}(x), n=0,1,... \] where and $B…
