DESCRIPTION:\n Moduli spaces of stable pointed curves play an important ro
le in algebraic geometry. This School will have one course on vector bundl
es of coinvariants and on conformal blocks and another one on their cohomo
logy classes in relation with those of moduli of abelian varieties. The co
homology of moduli spaces of curves and abelian varieties carries several
natural classes. We focus on the tautological classes and the cohomology c
lasses related to spaces of modular forms. The problem of determining rela
tionships between the tautological classes turns out to be particularly in
teresting. Moduli spaces of curves carry vector bundles of coinvariants an
d conformal blocks\; they are invariants of a curve C attached to a Lie gr
oup G that are canonically isomorphic to global sections of an ample line
bundle on the moduli stack of certain G-bundles on C. These are generalize
d theta functions in case C is smooth. In case g=0\, the bundles of co-inv
ariants are globally generated\, and their first Chern classes are semi-am
ple line bundles on the moduli of curves\, and shed light on its birationa
l geometry. We can also use the moduli space of curves to learn about gene
ralized theta functions.TOPICS:Cohomology classes on moduli of curves and
