The Emergence of Anticommuting Coordinates and the Dirac-Ramond-Kostant operators

چکیده
Gunnar Nordström died just a few years before the advent of quantum mechanics. It is is very interesting, but of course futile to speculate how he would have contributed to the new subject. His early attempts to increase the number of space dimensions [1] could very well have been very important for him when the spin degrees of freedom were understood. The birth of quantum mechanics in the 1920’s with the papers of Heisenberg [2] and Schrödinger [3] and others really made a quantum jump in our understanding of the microcosm. The formulation was revolutionary but treated space and time somewhat conservatively, since it was non-relativistic and the newly discovered spin degrees of freedom were just added on as multiplicative wave functions not connected to the 3-dimensional space. In the hectic year of 1926 Klein [4], Gordon [5] and Schrödinger [3] discussed the relativistic version and the KleinGordon equation was suggested.

Harmonic Spinors on Homogeneous Spaces
Let G be a compact, semi-simple Lie group and H a maximal rank reductive subgroup. The irreducible representations of G can be constructed as spaces of harmonic spinors with respect to a Dirac operator on the homogeneous space G/H twisted by bundles associated to the irreducible, possibly projective, representations of H. Here, we give a quick proof of this result, computing the index and kerne...
متن کاملDirac Operators and Lie Algebra Cohomology
Dirac cohomology is a new tool to study unitary and admissible representations of semisimple Lie groups. It was introduced by Vogan and further studied by Kostant and ourselves [V2], [HP1], [K4]. The aim of this paper is to study the Dirac cohomology for the Kostant cubic Dirac operator and its relation to Lie algebra cohomology. We show that the Dirac cohomology coincides with the correspondin...
