Duality theorems in conformal geometry,For conformally flat Riemannian manifolds of dimension n ≥ 3 ,we describe an explicit resolution of the sheaf Θ. of conformal Killing vector fields which is formally self-adjoint, and we deduce a duality theorem for the cohomology of X with values inΘ..

The DeSitter symmetry of the Dirac equation,The SO(4,1) symmetry of the Dirac equation is constructed. It is realized on the full space of solutions of the Dirac equation. Generalizations and possible physical implications are noted.

A new look at group orthogonality relations,Group orthogonality relations are presented in various coordinate-free, and possibly new, guises; it is . assumed that the ground field is algebraically closed. One of the more unlikely guises is used to give a basis-free proof of the “generalized Frobenius-Schur criterion” for the Wigner type of a corepresentation.
