Dowker %J Physics %D 1995 %I arXiv %R 10.1016/0370-2693(95)01376-8 %X Using known mode properties, the functional determinant for massless spin-half fields on the Euclidean 4-ball is calculated and shown to be different for spectral (nonlocal) and mixed (local) boundary conditions. The local result agrees with that from a conformal argument. Some higher-spin results are also given. %U http://arxiv.org/abs/hep-th/9508082v1
