Fourier Transforms of Lorentz Invariant Functions (2002)
Wurm, Alexander, Krausz, Nurit, DeWitt-Morette, Cecile, Berg, Marcus
Fourier transforms of Lorentz invariant functions in Minkowski space, with support on both the timelike and the spacelike domains are performed by means of direct integration. The cases of 1+1 and...
Supermanifolds - Application to Supersymmetry (2002)
Cartier, Pierre, DeWitt-Morette, Cecile, Ihl, Matthias, Saemann, Christian, Bell, Maria E.
Parity is ubiquitous, but not always identified as a simplifying tool for computations. Using parity, having in mind the example of the bosonic/fermionic Fock space, and the framework of Z_2-graded...

Cartier, Pierre, Berg, Marcus, DeWitt-Morette, Cecile, Wurm, Alex
Old and new results for characterizing volume forms in functional integration.
