Homogeneous foliations are easily classified via techniques that have been available for more than 30 years. The classification links such foliations to flat connections with values in the Lie algebra of the symmetry group. Classification of general foliations is far more difficult and attracted efforts of many mathematicians. The purpose of this talk is to show how a similar approach may be used to study (concordance classes of) arbitrary foliations of codimension 1, as the gauge equivalence classes of flat connections with values in smooth functions on real numbers. The talk is based on joint work with Mehrzad Ajoodanian
