It was recently proved by T. de Fernex and R. Docampo that the module of differentials of the algebra of Hasse-Schmidt derivations of a ring can be described in terms of the module of differentials of the ring. This result was then applied to find a projectivization of induced maps on jets schemes. In this talk, we explore the analogous statements for the module of high order differentials.

Joint work with Paul Barajas (Universidad Autónoma de Zacatecas).
