Periods of Quaternionic Shimura Varieties. I.Contemporary Mathematics, Volume: 762; 2021; 214 pp;  Softcover MSC: Primary 11; Print ISBN: 978-1-4704-4894-3, Product Code: CONM/762, List Price: $122.00

Authors: Atsushi Ichino: Kyoto University, Kyoto, Japan, Kartik Prasanna: University of Michigan, Ann Arbor, MI

This book formulates a new conjecture about quadratic periods of automorphic forms on quaternion algebras, which is an integral refinement of Shimura’s algebraicity conjectures on these periods.

P.R. Girard et al: Dual Hyperquaternion Poincaré Groups

Girard, P.R., Clarysse, P., Pujol, R., Goutte, R., Delachartre, P.: Dual Hyperquaternion Poincaré Groups. Adv. Appl. Clifford Algebras 31, 15 (2021). https://doi.org/10.1007/s00006-021-01120-z

Abstract. A new representation of the Poincaré groups in n dimensions via dual hyperquaternions is developed, hyperquaternions being defined as a tensor product of quaternion algebras (or a subalgebra thereof).
