5. 초록 : The projection of a variety from a point corresponds to the elimination of an ideal with respect to a variable. The theory of partial elimination ideals, initiated by Mark Green, provides a method to keep track of the algebraic properties of the projection. We discuss the depth and regularity of (inner) projection using partial elimination ideals. We also illustrate the applications of our results. This is work in progress with with D.T. Cuong and S. Kwak.
