I'm sorry if this question sounds a little vague.
I'm about to finish Fulton's algebraic curves book and I would like to know what's next. I'm looking for something deeper in algebraic curves. I'm a beginner in this subject and I'm felling a little lost.
Is there an "obvious" next step after study Riemann-Roch theorem? or it's depending of the branch you follow? if does, which branches can I follow?
Thanks in advance!
