Punctual Quot scheme on cusp via Gröbner stratification

Web1 The Hilbert scheme of points as a set There are several objects in mathematics which have the magical property of appearing in various areas and which are, therefore, of the greatest interest for mathematicians. One of those, of which we shall discuss in these notes, is the Hilbert scheme of points on a surface.
