Arrangements of curves and algebraic surfaces
Giancarlo Urzua
We prove a strong relation between Chern and log Chern invariants of algebraic surfaces. For a given arrangement of curves, we find nonsingular projective surfaces with Chern ratio…

On line arrangements with applications to 3-nets
Giancarlo Urzua
We show a one-to-one correspondence between arrangements of d lines in the projective plane, and lines in P^{d-2}. We apply this correspondence to classify (3,q)-nets over the comp…

Riemann Surfaces of genus g with an automorphism of order p prime and p>g
Giancarlo Urzua
The present work completes the classification of the compact Riemann surfaces of genus g with an analytic automorphism of order p (prime number) and p > g. More precisely, we const…
