1. Integrability Demand function x(p, w)(c d ) is HDO, satisfied walras law and have a substitution matriX S(p, w) is s n.s.d. for any (p, w), if it's deduced by rational preference And if we observed an x(p, w)satisfied such conditions, can we find a preference to rationalization x(p w ) That the integrability problem
