Deligne categories in lattice models and quantum field theory, or making sense of O(N) symmetry with non-integer N

Abstract When studying quantum field theories and lattice models, it is often useful to analytically continue the number of field or spin components from an integer to a real number. In spite of this, the precise meaning of such analytic continuations has never been fully clarified, and in particula...
