Getting around Antarctica: new high-resolution mappings of the grounded and freely-floating boundaries of the Antarctic ice sheet created for the International Polar Year
Antarctica the grounded freely-floating boundaries

Two ice-dynamic transitions of the Antarctic ice
sheet – the boundary of grounded ice features and the freely-floating boundary – are mapped at 15-m resolution by par-ticipants of the International P...

Firstly, we compute the distribution function for the hitting time of a linear time-dependent boundary t 7→ a + bt, a ≥ 0, b ∈ R, by a reflecting Brownian motion.
Some results concerning the $p$-Royden and $p$-harmonic boundaries of a graph of bounded degree

In this paper we consider two a priori very different problems: construction of the eigenstates of the spin chains with non parallel boundary magnetic fields and computation of the partition function ...
Quantum relaxation after a quench in systems with boundaries
Quantum relaxation boundaries

2010/11/23
We study the time-dependence of the magnetization profile, ml(t), of a large finite open quantum Ising chain after a quench. We observe a cyclic variation, in which starting with an exponentially decr...

2010/11/11
We obtain a new representation for the partition function of the six vertex model with domain wall boundaries using a functional equation recently derived by the author. This new representation is giv...
Inertial forces and dissipation on accelerated boundaries

2010/11/9
We study dissipative effects due to inertial forces acting on matter fields confined to accelerated boundaries in $1+1$, $2+1$, and $3+1$ dimensions. These matter fields describe the internal degrees ...
Cell-Like Equivalences and Boundaries of CAT(0) Groups
Cell-Like Equivalences Boundaries of CAT(0) Groups
font style='font-size:12px;'>
2010/11/11
In 2000, Croke and Kleiner showed that a CAT(0) group G can admit more than one boundary. This contrasted with the situation for word hyperbolic groups, where it was well-known that each such group a...
Virtual boundaries of Hadamard spaces with admissible actions of higher rank
Hadamard spaces math
font style='font-size:12px;'>
2010/11/19
Any discrete action of a group on a locally compact Hadamard space extends to a topological action on the virtual boundary. Croke and Kleiner introduced a class of so-called admissible actions and as...
