Let $X$ a complex curve and $x\in X$ a point. We consider the space of divisors $D$ with fixed degree $d$, with no multiplicity outside the point $x$ and with multiplicity less or equal than 2 at $x$? Why this space is not open? Now, we consider the same space of divisors $D$ with fixed degree $d$ such that: $\sum\limits_{x untransversal}m_{x}(D)\leq N.$ where the untransversal points means that $m_{x}(D)\geq 2$. Is this space open?
