Tóm tắt: 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 finer properties of the projection. We introduce partial elimination ideals, their computations with computer algebra softwares, and a few examples. We introduce some techniques to study partial elimination ideals.
