Let G be a real reductive Lie group with maximal compact subgroup K. We generalize the usual notion of Dirac index to a twisted version, which is nontrivial even in cases when G and K do not have equal rank. We compute ordinary and twisted indices of standard modules. As applications, we study extensions of Harish-Chandra modules and twisted characters. [ABSTRACT FROM AUTHOR] |
