Heat conduction through permafrost and its potential for explosive behavior
Kaitlin Hill, Richard McGehee
The recent widespread thaw of permafrost has led to observations of explosive gas emissions, which expel ice and soil debris and leave behind large craters. This phenomenon appears…

Affine map equivalence versus critical set equivalence for quadratic maps of the plane
Chia-Hsing Nien, Bruce B. Peckham, Richard P. McGehee
In recent work [Nien et al. 2016], the authors enumerated a classification of quadratic maps of the plane according to their critical sets and images. It is straightforward to show…

Classification of critical sets and their images for quadratic maps of the plane
Chia-Hsing Nien, Bruce B. Peckham, Richard P. McGehee
We provide a complete classification of the critical sets and their images for quadratic maps of the real plane. Critical sets are always conic sections, which provides a starting…
