SUMMARY:Workshop / Seminar:GLNT: Maximal Integral Orthogonal Groups
DESCRIPTION:We work out the maximal arithmetic subgroups of every orthogonal group G over the rational numbers (indefinite with dimension at least 3). The final answer is quite clean\, but has some interesting exceptional cases. The local analysis has two main ingredients: first\, new building-like complexes on which p-adic orthogonal groups act\; second\, a very detailed analysis of how the stabilizer of each vertex permutes its neighbors. The strong approximation theorem isn't quite enough to pass to the global case: for some quadratic forms over Z we must also construct reflections in their orthogonal groups. Our paper\, giving all details\, is available at https://web.ma.utexas.edu/users/allcock/research/omax12.pdf

SUMMARY:Workshop / Seminar:Gomberg Lecture: Ruminations in Inorganic and Organometallic Chemistry by a Grumpy Old Man
DESCRIPTION:This lecture will be a potpourri of chemistry that reflects: 1) teachings that are either inaccurate or puzzling\; 2) attempts to broaden the redox capability of base metals\, and accompanying electronic structure evaluations\; 3) generally increasing confusion among students.
