On motives for cusp forms -- Carel Faber

Consani and I have recently obtained a new construction of the motives corresponding to cusp forms in genus 1 and level 1 occurring in the cohomology of Mbar_{1,n}. I will discuss this construction. If time permits, the situation in higher genus and higher level will be considered as well.
