On groups and counter automata

Murray Elder, Mark Kambites, Gretchen Ostheimer

We study finitely generated groups whose word problems are accepted by counter automata. We show that a group has word problem accepted by a blind n-counter automaton in the sense…

Nonuniform mixed-parity superfluid state in Fermi gases

K. V. Samokhin, M. S. Mar'enko

We study the effects of dipole interaction on the superfluidity in a homogeneous Fermi gas with population imbalance. We show that the Larkin-Ovchinnikov-Fulde-Ferrell phase is rep…

The Expansion Asymmetry and Age of the Cassiopeia A Supernova Remnant

R. A. Fesen, M. C. Hammell, J. Morse +7

HST ACS images of the young SN remnant Cas A are used to explore the expansion and spatial distribution of its highest velocity debris. Proper motions of over 1800 outlying ejecta…

Evolution of the Reverse Shock Emission from SNR 1987A

Kevin Heng, Richard McCray, Svetozar A. Zhekov +13

We present new (2004 July) G750L and G140L Space Telescope Imaging Spectrograph (STIS) data of the H-alpha and Ly-alpha emission from supernova remnant (SNR) 1987A. With the aid of…

Infinite time computable model theory

Joel David Hamkins, Russell Miller, Daniel Seabold +1

We introduce infinite time computable model theory, the computable model theory arising with infinite time Turing machines, which provide infinitary notions of computability for st…
