Groupoid Actions on Fractafolds [PDF]

open access: yes, 2014
We define a bundle over a totally disconnected set such that each fiber is homeomorphic to a fractal blowup. We prove that there is a natural action of a Renault-Deaconu groupoid on our fractafold bundle and that the resulting action groupoid is a ...

Explicit rank bounds for cyclic covers [PDF]

open access: yes, 2015
Let $M$ be a closed, orientable hyperbolic 3-manifold and $\phi$ a homomorphism of its fundamental group onto $\mathbb{Z}$ that is not induced by a fibration over the circle.

Frustration of Bragg reflection by cooperative dual-mode interference: a new mode of optical propagation [PDF]

open access: yes, 1998
A new optical mode of propagation is described, which is the natural eigenmode (supermode) of a fiber (or any optical waveguide) with two cospatial periodic gratings.
