Divisorial condition for the stable gonality of tropical curves. (arXiv:1801.07405v2 [math.AG] UPDATED)

来源于:arXiv
Let d be a positive integer. There are several versions of d-gonality for tropical curves, stable d-gonality and divisorial d-gonality, which are both inspired by d-gonality for compact Riemann surfaces. However, that conditions are not equivalent. We have a condition of divisors equivalent to stable d-gonality for tropical curves. 查看全文>>
