| Abstract |
We compute the cohomology of the stackM1 over C with coefficients in Z[12 ], and in low degrees with coefficients in Z. Cohomology classes onM1 give rise to characteristic classes, cohomological invariants of families of curves of genus one. We prove a number of vanishing results for those characteristic classes and give explicit examples of families with nonvanishing characteristic classes. |
