To (sg)u2 m 53(r) where rno is the bare mass of the particle and 5'(r) is invariantly defined in three-space as a The infinite mass self-energy difficulties of quantum field theory already occur, as is wellknown, in the corresponding classical theories. Although cutoffs may be introduced to effect re-
