Tóm tắt: When generalizing Yasuda's higher Nash blowup to that of any morphism of varieties it arises a standard sheaf of ideals which plays the role of a center of an isomorphic blow up. Working with regular functions on smooth varieties, we develop some essential relations of this sheaf of ideals with contact equivalence of complex analytic germs and motivic zeta functions.
