Anticipating Reflected Stochastic Differential Equations
Zongxia Liang, Tusheng Zhang
In this paper, we establish the existence of the solutions of reflected stochastic differential equations with possible anticipating initial random variables. The key is…
On symmetric invariants of centralisers in reductive Lie algebras
D. Panyushev, A. Premet, O. Yakimova
Let be the centraliser of a nilpotent element in a finite dimensional simple Lie algebra of rank over an algebraically closed field of characteristic 0. We invest…
Getting Its Kicks: A VLBA Parallax for the Hyperfast Pulsar B1508+55
S. Chatterjee, W. H. T. Vlemmings, W. F. Brisken +7
The highest velocity neutron stars establish stringent constraints on natal kicks, asymmetries in supernova core collapse, and the evolution of close binary systems. Here we presen…
Pulsar Astrometry at the Microarcsecond Level
W. H. T. Vlemmings, S. Chatterjee, W. F. Brisken +12
Determination of pulsar parallaxes and proper motions addresses fundamental astrophysical questions. We have recently finished a VLBI astrometry project to determine the proper mot…
Spin-enhanced magnetocaloric effect in molecular nanomagnets
Marco Evangelisti, Andrea Candini, Alberto Ghirri +3
An unusually large magnetocaloric effect for the temperature region below 10 K is found for the Fe14 molecular nanomagnet. This is to large extent caused by its extremely large spi…
Factorisation of Lie Resolvents
R. M. Bryant, M. Schocker
Let be a group, a field of prime characteristic and a finite-dimensional -module. Let denote the free Lie algebra on , regarded as an -module, and…
