| Abstract: | In this note we compute the scrollar invariants of certaind-gonal curves (e.g. Castelnuovo curves and bielliptic curves) by using appropriate plane models. Ford=4 andg(C)≥10, we show that those invariants discriminate bielliptic curves among tetragonal ones.
Sunto In questa nota si determinano gli invarianti scrollari per alcuni tipi di curved-gonaliC (ad esempio curve di Castelnuovo, curve biellittiche) tramite appropriati modelli piani. Perd=4 eg(C)≥10, si mostra che tali invarianti individuano le curve biellittiche fra le tetragonali.
