“…Finally we mention very briefly our motivation, related known results and some perspective questions. Firstly the exact appearance of SL(2, R) β G = Sp(2, R) and the corresponding branching problem can be used to study the induced representation of the group G 2 from its Heisenberg parabolic subgroup [7]; in [8] we shall study the non-compact realization of induced represenations for Hermitian Lie groups using the related branching of metaplectic representation, the compact picture being studied in [22]. Next this kind of branching problem can be formulated for any real split simple Lie group G. Indeed up to conjugation there is a unique principal subalgebra sl(2, R) (and it might have more than one principal sl(2, R)-subgroups); see [14].…”

Sp(2, \mathbb R)

SL(2, \mathbb R)

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citationsβcitations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
