The curvature of left-invariant magnetic systems
Shane Rankin, Ivo Terek, David Weed
We compute the magnetic curvatures (in the sense of Assenza) of left-invariant magnetic systems on Lie groups and explore relations between curvature properties and algebraic prope…

Face embeddings of Archimedean solids
Tommy Murphy, David Weed
We characterize the Archimedean solids among the convex uniform polyhedra via face embeddings into a regular Tetrahedron. This result has been listed without proof in the literatur…

Computing with FRACTRAN
Khushi Kaushik, Tommy Murphy, David Weed
The FRACTRAN programs GAME and NRGAME are presented, both of which compute the decimal expansion of . Our GAME is analogous to Conway's PIGA…
