canonicalDivisorM0nbar -- returns the class of the canonical divisor on the moduli space of stable n-pointed genus 0 curves

Synopsis

Usage:
canonicalDivisorM0nbar(14)
Inputs:
- n, an integer
Outputs:
- K, an object of class SymmetricDivisorM0nbar

Description

This function returns the class of the canonical divisor K on the moduli space M_0,n. See e.g. [KM] for a formula for K in the standard basis.
