Relations in the Canonical Algebras on Surfaces

open access: yesRendiconti del Seminario Matematico della Università di Padova, 2008
The degree bound for primitive generators and relations of the canonical ring of a minimal surface of general type are studied via Green’s Koszul cohomology, assuming that the fixed part of the canonical linear system does not contain any Francia cycles. Slight refinements of the results due to Ciliberto and Reid are given.

SOME SURFACES OF SECOND ORDER AS EXAMPLES OF WEBER`S SURFACES

open access: yesJournal of Industrial Design and Engineering Graphics, 2015
In this paper we consider some surfaces of second order as surfaces generated from focaldirectorial elements (point, line, plane). Extraction of parts of the surface according to appropriate algebraic-geometric conditions will also be defined.
