Karamata's theorem for regularised Cauchy transforms

Matthias Langer, Harald Woracek

We prove Abelian and Tauberian theorems for regularised Cauchy transforms of positive Borel measures on the real line whose distribution functions grow at most polynomially at infi…

The Radial Hedgehog Solution in the Landau-de Gennes Theory: Effects of the Bulk Potentials

Sophie McLauchlan, Yucen Han, Matthias Langer +1

We study equilibrium configurations in spherical droplets of nematic liquid crystal with strong radial anchoring, within the Landau-de Gennes theory with a sixth-order bulk potenti…

Discrete fragmentation equations with time-dependent coefficients

Lyndsay Kerr, Wilson Lamb, Matthias Langer

We examine an infinite, linear system of ordinary differential equations that models the evolution of fragmenting clusters, where each cluster is assumed to be composed of identica…

Canonical systems whose Weyl coefficients have dominating real part

Matthias Langer, Raphael Pruckner, Harald Woracek

For a two-dimensional canonical system on the half-line whose Hamiltonian is a.e. positive semi-definite, denote by its Weyl coefficient.…

Estimates for the Weyl coefficient of a two-dimensional canonical system

Matthias Langer, Raphael Pruckner, Harald Woracek

For a two-dimensional canonical system on some interval whose Hamiltonian is a.e. positive semi-definite and which is regular at and in the limit…

Discrete fragmentation systems in weighted spaces

Lyndsay Kerr, Wilson Lamb, Matthias Langer

We investigate an infinite, linear system of ordinary differential equations that models the evolution of fragmenting clusters. We assume that each cluster is composed of identical…
