An exception is the standard ensemble for the study of XOR-SAT problems , which is essentially a particular case of our model, but the matrices J are constrained to have a fixed number of non-zero entries per row, and do not have any constraint on the columns.
General duality for abelian-group-valued statistical-mechanics models
Proof: The proof of this result is essentially contained in that of Theorem 6.4; the restriction on the constant σ there arises from the requirement that the full non-linear constraint map be well defined, but this restriction is not needed for the linearised problem.
