The multiple-point schemes of a finite curvilinear map of codimension one

Steven Kleiman, Joseph Lipman, Bernd Ulrich

Let X and Y be smooth varieties of dimensions n-1 and n over an arbitrary algebraically closed field, f:X-> Y a finite map that is birational onto its image. Suppose that f is curv…

Adjoints of ideals in regular local rings

Joseph Lipman

The adjoint of an ideal I in a regular local ring R is the R-ideal adj(I):=H^0(Y, Iω_Y), where f:Y -> Spec(R) is a proper birational map with Y nonsingular and IO_Y invertible, and…
