Gross-Neveu Models, Nonlinear Dirac Equations, Surfaces and Strings

, 2010
Recent studies of the thermodynamic phase diagrams of the Gross-Neveu model (GN2), and its chiral cousin, the NJL2 model, have shown that there are phases with inhomogeneous crystalline condensates.

Periodic boundary conditions on the pseudosphere

, 2007
We provide a framework to build periodic boundary conditions on the pseudosphere (or hyperbolic plane), the infinite two-dimensional Riemannian space of constant negative curvature.

Strong-field tidal distortions of rotating black holes: III. Embeddings in hyperbolic 3-space

, 2017
In previous work, we developed tools for quantifying the tidal distortion of a black hole's event horizon due to an orbiting companion. These tools use techniques which require large mass ratios (companion mass $\mu$ much smaller than black hole mass $M$)

Discrete constant mean curvature nets in space forms: Steiner's formula and Christoffel duality

, 2014
We show that the discrete principal nets in quadrics of constant curvature that have constant mixed area mean curvature can be characterized by the existence of a K\"onigs dual in a concentric quadric.Comment: 12 pages, 10 figures, pdfLaTeX (plain pdfTeX

Convergence and Optimality of Adaptive Mixed Methods on Surfaces [PDF]

, 2014
In a 1988 article, Dziuk introduced a nodal finite element method for the Laplace-Beltrami equation on 2-surfaces approximated by a piecewise-linear triangulation, initiating a line of research into surface finite element methods (SFEM). Demlow and Dziuk

On Isosystolic Inequalities for T^n, RP^n, and M^3

, 2013
If a closed smooth n-manifold M admits a finite cover whose Z/2Z-cohomology has the maximal cup-length, then for any riemannian metric g on M, we show that the systole Sys(M,g) and the volume Vol(M,g) of the riemannian manifold (M,g) are related by the ...

Some Aspects of the AdS/CFT Correspondence

, 2004
This is a very brief review of some aspects of the AdS/CFT correspondence with an emphasis on the role of the topology of the boundary and the meaning of the sum over bulk geometries.
