Quasisymmetric Maps on the Boundary of a Negatively Curved Solvable Lie Group
Xiangdong Xie
We describe all the self quasisymmetric maps on the ideal boundary of a particular negatively curved solvable Lie group. As applications, we prove a Liouville type theorem, and der…
Homological dimensions and regular rings
Alina Iacob, Srikanth B. Iyengar
A question of Avramov and Foxby concerning injective dimension of complexes is settled in the affirmative for the class of noetherian rings. A key step in the proof is to recast th…
Generalized complex hamiltonian torus actions: Examples and constraints
Thomas Baird, Yi Lin
Consider an effective Hamiltonian torus action on a topologically twisted,generalized complex manifold of dimension . We prove that the …
Dark Matter Halos and Evolution of Bars in Disk Galaxies: Collisionless Models Revisited
Jorge Villa-Vargas, Isaac Shlosman, Clayton Heller
We construct and evolve families of steady-state models of stellar disks embedded in live DM halos, in order to study the dynamical and secular phases of bar evolution. These model…
Dissecting Galaxy Formation: I. Comparison Between Pure Dark Matter and Baryonic Models
Emilio Romano-Diaz, Isaac Shlosman, Clayton Heller +1
We compare assembly of DM halos with and without baryons, within the context of cosmological evolution in the LCDM WMAP3 Universe (baryons+DM, BDM model, and pure DM, PDM model). I…
