Seshadri constants, gonality of space curves and restriction of stable bundles
Roberto Paoletti
We define the Seshadri constant of a space curve and consider ways to estimate it. We then show that it governs the gonality of the curve. We use an argument based on Bogomolov's i…

Free pencils on divisors
Roberto Paoletti
Let X be a smooth projective variety defined over an algebraically closed field, and let Y in X be a reduced and irreducible ample divisor in X. We give a numerical sufficient cond…

On the surjectivity of Wahl maps on a general curve
Roberto Paoletti
This paper explores the geometric meaning of the failure of certain kinds of Wahl maps to surject on a general curve. Sufficient conditions for surjectivity are given. An approach…
