one represented by a totally unimodular matrix M); when M is the boundary matrix of a cell complex, this is the case where the torsion coefficients are all trivial.
Note that if indeed d = 1, then all the torsion coefficients are 1; [mu] is just the number of vertices of [SIGMA]; and for any edge [sigma] in [gamma], the vector [chi]([gamma], [sigma]) is the usual signed characteristic vector of the fundamental bond bo([gamma], [sigma]).
