Webequivalent. The easiest way to prove this is via the Hammersley-Clifford theorem: In the Hammersley-Clifford theorem, we only make use of pairwise independencies to prove the existence of a factorization. (I would strongly encourage you to look at the proof and verify this). Thus, for a positive distribution, we have: WebClifford Henry Taubes (born February 21, 1954) [1] is the William Petschek Professor of Mathematics at Harvard University and works in gauge field theory, differential geometry, and low-dimensional topology.

Clifford's theorem yields information about the restriction of a complex irreducible character of a finite group G to a normal subgroup N. If μ is a complex character of N, then for a fixed element g of G, another character, μ (g), of N may be constructed by setting () = for all n in N.
