Parsec-scale magnetic fields in Arp 220
James McBride, Timothy Robishaw, Carl Heiles +2
We present the first very-long-baseline interferometry (VLBI) detections of Zeeman splitting in another galaxy. We used Arecibo Observatory, the Green Bank Telescope, and the Very…
Drawing Partially Embedded and Simultaneously Planar Graphs
Timothy M. Chan, Fabrizio Frati, Carsten Gutwenger +3
We investigate the problem of constructing planar drawings with few bends for two related problems, the partially embedded graph problem---to extend a straight-line planar drawing…
-trace identities and invariant theory
Allan Berele
We generalize the notion of trace identity to -trace. Our main result is that all -traces of are consequence of those of degree . This also gives a…
Six-vertex model with partial domain wall boundary conditions: ferroelectric phase
Pavel Bleher, Karl Liechty
We obtain an asymptotic formula for the partition function of the six-vertex model with partial domain wall boundary conditions in the ferroelectric phase region. The proof is base…
On the expected number of commutations in reduced words
Bridget Eileen Tenner
We compute the expected number of commutations appearing in a reduced word for the longest element in the symmetric group. The asymptotic behavior of this value is analyzed and sho…
The Steinberg torus of a Weyl group as a module over the Coxeter complex
Marcelo Aguiar, T. Kyle Petersen
Associated to each irreducible crystallographic root system , there is a certain cell complex structure on the torus obtained as the quotient of the ambient space by the coroot…
