Dirac cohomology of Wallach representations
We compute the Dirac cohomology of the unitary Harish-Chandra modules for classical groups lifted from 1- dimensional representations of the compact factors in Howe duality, including all Wallach modules. Our approach is based on the explicit knowledge of the $K$-types of these Harish-Chandra modules and of the spinor module for the maximal compact subgroup. Our description of the Dirac cohomology is an explicit pairing between these $K$-types in terms of their PRV components.
