Trieste summer school, ICTP, September 2002
Here are preliminary transparencies for lectures:
- Part 1, Moduli of Twisted Stable Maps, in
postscript,
dvi, or
the TEX source.
- Part 2, Quantum Cohomology of Orbifolds, in
postscript,
dvi, or
the TEX source.
- Part 3, Stringy Orbifold Cohomology: Theory and Examples, in
postscript,
dvi, or
the TEX source.
here is the paper "Algebraic Orbifold Quantum products", by Tom Graber,
Angelo Vistoli and me, on which the course is based. In
postscript or
dvi
A hopefully reasonable introduction for part 1 is in
Complete moduli for families over semistable curves, written by Angelo
Vistoli and me.
The work of Weimin
Chen and Yongbin Ruan:
A New Cohomology Theory for Orbifold,
Orbifold Quantum Cohomology, and
Orbifold Gromov-Witten Theory
The paper
