Very ample linear series on quadrigonal curves
Marc Coppens, Gerriet Martens
In this paper we describe all complete and very ample linear series on 4-gonal smooth curves.
The scrollar invariants of k-gonal curves having a nodal model on a smooth quadric having its nodes on few lines
Marc Coppens
We determine the scrollar invariants of the normalization of a nodal curve of type on a smooth quadric associated to the …
The uniqueness of Weierstrass points with semigroup <a;b> and related subgroups
Marc Coppens
Assume and with and are relatively prime integers. In case is a smooth curve and is a point on with Weierstrass semigroup equal to $<a;b…
A metric graph satisfying that cannot be lifted to a curve satisfying
Marc Coppens
For all integers we prove the existence of a metric graph with such that has Clifford index 2 and there is no tropical modification of such th…
Free divisors on metric graphs
Marc Coppens
On a metric graph we introduce the notion of a free divisor as a replacement for the notion of a base point free complete linear system on a curve. By means of an example we show t…
Clifford's Theorem for graphs
Marc Coppens
Let be a metric graph having a linear system for some then has a linear system . This is similar to the well-known Clifford's Theorem…
