A note on axial symmetries [PDF]

open access: yesarXiv, 2013
This note describes a local scheme to characterize and normalize an axial Killing field on a general Riemannian geometry. No global assumptions are necessary, such as that the orbits of the Killing field all have period $2 \pi$. Rather, any Killing field that vanishes at at least one point necessarily has the expected global properties.

Negative density-dependent dispersal of the mountain pine beetle in Alberta [PDF]

open access: yesarXiv
Understanding the mountain pine beetle's dispersal patterns is critical for evaluating its threat to Canada's boreal forests. It is generally believed that higher beetle densities lead to increased long-distance dispersal due to aggregation pheromones becoming repellent at high densities, causing beetles to seek areas with less competition.

The Flea on the Magnetic Elephant [PDF]

open access: yesarXiv
We investigate a two-dimensional magnetic Laplacian with two radially symmetric magnetic wells. Its spectral properties are determined by the tunneling between them. If the tunneling is weak and the wells are mirror symmetric, the two lowest eigenfunctions are localized in both wells being distributed roughly equally.
