Alternating groups and rational functions on surfaces

Sonia Brivio, Gian Pietro Pirola

Let X be a smooth complex projective surface. We prove that for any sufficiently big m there exists a rational dominant map f from X into a complex rational ruled surface Y, such t…

Algebraic functions with even monodromy

Michela Artebani, Gian Pietro Pirola

Let $X$ be a compact Riemann surface of genus $g$ and $d \geq 12 g + 4$ be an integer. We show that $X$ admits meromorphic functions with monodromy group equal to the alternating group…

Hodge-Gaussian maps

Elisabetta Colombo, Gian Pietro Pirola, Alfonso Tortora

Let $X$ be a compact Kähler manifold, and let $L$ be a line bundle on $X .$ Define $I_{k} (L)$ to be the kernel of the multiplication map $S y m^{k} H^{0} (L) \to H^{0} (L^{k}) .$ For all $h \le…
