... fermionic coordinates of spacetime. The idea of bosonic deformations of spacetime coordinates can in fact be traced back to work by H. S. Snyder in 1947 [262]. In the case of fermionic coordinates, ... new particle accelerator at CERN, which will start collecting data in 2007.

... fermions. A large class of such theories can be constructed by taking the OPE closure of some subspace of F N and factoring out those fields which have identically vanishing n-point functions. One example ... (17) Given the structure constants d ab and f abc , this is sufficient to calculate all n- point functions of the theory, since by induction one knows all singular terms of these meromor...

... by comparing the first Fourier coefficient one gets c m (n)=λ m (n )c 1 . Assuming c 1 = 0 and using a convenient normalization c 1 = 1 one concludes that eigenvalues of the Hecke operators coincide ... this Section is to calculate the two-point correlation function of modular group multiplicities, γ(r), whose Fourier harmonics according to (84) determines the two-point correlation form...
