I need help with this exercise:
Show that the group law of a complex torus (the definition I have is that of Rick Miranda's book Algebraic curves and Riemann surfaces, the one that he constructs from a lattice) X is divisible: for any point $p\in X$ and any integer $n\geq 1$ here is a point $q\in X$ with $n*q=p$. Indeed, show that there are exactly $n^2$ such points.
Thanks.
