Seventeen papers from a July 2001 workshop present recent developments in geometric and arithmetic methods for studying mirror symmetry, particularly for counting the number of rational curves on Calabi-Yau threefolds. The contributors explore a toric geometry approach to Calabi-Yau manifolds, Picar «
