Let X be an algebraic curve and c be the Clifford index of X. When c is small (e.g c=1), what is the classification of the line bundle who computes c?

I know this is an old question (ok, two weeks, whatever) but my guess as to why you haven't gotten any responses is that your question is terribly vague. What are you looking for exactly? A means of constructing a line bundle achieving the bound? Also, you've given no motivation whatsoever, merely asked a hard-to-follow question. I'll gladly attempt to answer the question, once I'm more certain of what it is. – Charles Siegel Jan 7 at 14:36

How to write math

You can just type LaTeX formulas between dollar signs! There are still some bugs with the preview; see the FAQ and this meta.MO thread for details. Basic solution: if you're having problems with the preview (or the post looks wrong), put backticks around any math that contains underscores or asterisks. E.g. write `$f'_n=g_{n+1}$`.

Since jsMath does take some time to render mathematical markup (for some people it's quite slow), please consider using basic HTML and HTML symbols for simple formulas whenever possible, like λ<sup>1</sup> ∉ ℤ<sub>p</sub> to get λ¹ ∉ ℤ_p.
