The systematic use of Koszul cohomology computations in algebraic geometry might be traced again to the foundational paintings of Mark eco-friendly within the Nineteen Eighties. eco-friendly attached classical effects about the perfect of a projective type with vanishing theorems for Koszul cohomology. eco-friendly and Lazarsfeld additionally acknowledged conjectures that relate the Koszul cohomology of algebraic curves with the lifestyles of specific divisors at the curve. those conjectures grew to become an incredible instruction for destiny study. within the intervening years, there was a growing to be interplay among Koszul cohomology and algebraic geometry. eco-friendly and Voisin utilized Koszul cohomology to a couple of Hodge-theoretic difficulties, with amazing luck. extra lately, Voisin completed a step forward by means of proving Green's conjecture for normal curves; quickly afterwards, the Green-Lazarsfeld conjecture for normal curves used to be proved to boot. This ebook is essentially taken with purposes of Koszul cohomology to algebraic geometry, with an emphasis on syzygies of advanced projective curves. The authors' major objective is to give Voisin's evidence of the commonplace eco-friendly conjecture, and next refinements. They speak about the geometric features of the speculation and a couple of concrete functions of Koszul cohomology to difficulties in algebraic geometry, together with purposes to Hodge conception and to the geometry of the moduli area of curves.
