Witrynagenerators are traceless Hermitian matrices. What Lie group do we get if we exponentiate only these generators, that is if we consider those unitary matrices with U= exp(i iX i)? We get the group SU(2). Remembering that SU(2) is the group of unitary matrices with unit determinant, this follows from the same determinant identity Eq. … Witryna15 kwi 2024 · Let G be an irreducible Hermitian Lie group and D = G / K its bounded symmetric domain in C d of rank r. Each γ of the Harish-Chandra strongly orthogonal roots {γ 1, ⋯, γ r} defines a Heisenberg parabolic subgroup P = M A N of G. We study the principal series representations Ind P G (1 ⊗ e ν ⊗ 1) of G induced from P.
