Holomorphic language for \(\overline\partial\)-cohomology and representations of real semisimple Lie groups. (English) Zbl 0808.55006
Eastwood, Michael (ed.) et al., The Penrose transform and analytic cohomology in representation theory. AMS-IMS-SIAM summer research conference, June 27 - July 3, 1992, South Hadley, MA, USA. Providence, RI: American Mathematical Society. Contemp. Math. 154, 103-115 (1993).
The author describes a continuous version of Čech cohomology, related to special Stein coverings, indexed by a differentiable manifold, of some complex manifolds, e.g. flag manifolds or pseudo Hermitian symmetric manifolds. Applications are given to hyperfunctions, non-holomorphic discrete series for \(\text{SU}(2,1)\), Speh representations of \(\text{SL} (2n,\mathbb{R})\).
For the entire collection see [Zbl 0780.00026].
