Given a long exact sequence of abelian groups $L:\,\, \cdot \cdot \cdot \to {L^{i - 1}\underrightarrow {{\xi ^{i - 1}}}\,{L^i}\,\underrightarrow {{\xi ^{i - 1}}}\,{L ...
Baker-Beyon duality theory yields a concrete representation of any finitely generated projective Abelian lattice-ordered group G in terms of piecewise linear homogeneous functions with integer ...
