Octonions and the rolling ball - Part 2 |
*The three R-groups: Knapp-Stein, Langlands-Arthur, and Endoscopic, play a crucial role in the study of reducibility of parabolic induction of algebraic groups over a local field and contribute to the endoscopic classification of automorphic representations of those over global fields. In talk I and II, we shall introduce those R-groups, and discuss a conjectural isomorphism between the Knapp-Stein and Langlands-Arthur R-groups, so-called Arthur's conjecture, mainly focusing on simply connected cases - p-adic SU(n), Spin(n) and their inner forms. These talks are based on joint work with D. Goldberg and another with D. Ban and D. Goldberg.

Improving a result of Maltsev on Heisenberg Groups* |
*Abstract: In the 1930s, Maltsev proved that the Heisenberg group of a field, even considered as an abstract group, carries a lot of information about the field. Indeed, in unpublished work from 2005, Calvert, Harizanov, Knight, and Morozov showed that, using any non‐commuting pair of elements as parameters, one can define a field in this abstract group which is isomorphic to the original field. Those parameters matter, though, and can create significant technical difficulties when we try to apply this result.
Using some recent work of Harrison‐Trainor, Melnikov, Miller, and Montalban on computable functors and effective interpretations, we have recently improved this result. We now have an interpretation of the original field with no parameters at all. This highly uniform result is an improvement over what we knew before, and tells us that even 2‐step nilpotent groups are even more complicated than we knew.
