A geometric approach to the transport of discontinuous densities
Caroline Moosmüller, Felix Dietrich, Ioannis G. Kevrekidis
Different observations of a relation between inputs ("sources") and outputs ("targets") are often reported in terms of histograms (discretizations of the source and the target dens…

Polynomial overreproduction by Hermite subdivision operators, and -Cauchy numbers
Caroline Moosmüller, Tomas Sauer
We study the case of Hermite subdivision operators satisfying a spectral condition of order greater than their size. We show that this can be characterized by operator factorizatio…

Stirling numbers and Gregory coefficients for the factorization of Hermite subdivision operators
Caroline Moosmüller, Svenja Hüning, Costanza Conti
In this paper we present a factorization framework for Hermite subdivision schemes refining function values and first derivatives, which satisfy a spectral condition of high order.…
