模群的完全型与上同调

Perfect forms and the cohomology of modular groups

Philippe Elbaz-Vincent, Herbert Gangl, Christophe Soulé

摘要:

对于N= 5,6和7,利用完全二次型的分类,我们计算了附在模群SL_N(\Z)和GL_N(\Z)上的Voronoi胞腔复形的同调.由此我们推导出这些群的有理上同调。

英文摘要:

For N=5, 6 and 7, using the classification of perfect quadratic forms, we compute the homology of the Voronoi cell complexes attached to the modular groups SL_N(\Z) and GL_N(\Z). From this we deduce the rational cohomology of those groups.
