On small homotopies of loops
G. Conner, M. Meilstrup, D. Repovš +2
Two natural questions are answered in the negative: (1) If a space has the property that small nulhomotopic loops bound small nulhomotopies, then are loops which are limits of nulh…
Photoionization of Clustered Halos by the First Stars
Daniel Whalen, Brian W. O'Shea, Joseph Smidt +1
We present numerical simulations of the photoevaporation of cosmological halos clustered around a 120 M primordial star, confining our study to structures capable of hostin…
Simulating binary neutron stars: dynamics and gravitational waves
Matthew Anderson, Eric W. Hirschmann, Luis Lehner +5
We model two mergers of orbiting binary neutron stars, the first forming a black hole and the second a differentially rotating neutron star. We extract gravitational waveforms in t…
Initial mass function effects on the colour evolution of disk galaxies
P. Westera, M. Samland, S. J. Kautsch +2
In this work, we want to find out if the IMF can be determined from colour images, integrated colours, or mass-to-light ratios, especially at high redshift, where galaxies cannot b…
Constructing subdivision rules from rational maps
J. W. Cannon, W. J. Floyd, W. R. Parry
This paper deepens the connections between critically finite rational maps and finite subdivision rules. The main theorem is that if f is a critically finite rational map with no p…
Slope lengths and generalized augmented links
Jessica S. Purcell
In this paper, we determine geometric information on slope lengths of a large class of knots in the 3-sphere, based only on diagrammatical properties of the knots. In particular, w…
