Similarity:

Here we study the gonality of several projective curves which arise in a natural way (e.gċurves with maximal genus in $𝐏^{n}$ , curves with given degree $d$ and genus $g$ for all possible $d$ , $g$ if $n = 3$ and with large $g$ for arbitrary $(d, g, n)$ ).

Similarity:

Here we prove a numerical bound implying that, except for smooth plane conics in characteristic 2, no complete linear system maps birationally a smooth curve into a projective space with a strange curve as image.

Similarity:

Let X be a smooth connected projective curve of genus g defined over R. Here we give bounds for the real gonality of X in terms of the complex gonality of X.
