| Abstract |
By associating to a curve C and a g'd the so-called trace curve and reduced trace curve we define two rational maps 0 and 0 from the Hurwitz space of admissible covers of genus g=2k and degree d=k+1 to moduli spaces Mg' and Mg . We study the induced map of the divisor class group of Mg' and Mg to the divisor class group of Mg. |
