For a nondegenerate irreducible projective variety, it is a clas- sical problem to describe its defining equations. In this paper we precisely determine the defining equations of some rational curves of maximal reg- ularity in P4 according to their rational parameterizations.

Abstract

For a nondegenerate irreducible projective variety, it is a clas- sical problem to describe its defining equations. In this paper we precisely determine the defining equations of some rational curves of maximal reg- ularity in P4 according to their rational parameterizations.
