我们将Sullivan有理同伦理论推广到一类有限指标范畴上的单连通空间的图表,构造了其几何与代数最小模型。这两类模型都分类有理图表的同伦类型,但其最小性条件可能不同。我们还表明,与经典有理同伦理论相反,H-图表不必分裂为Eilenberg--MacLane图表的乘积,并刻画了使得每个H-图表都允许这种分裂的指标范畴。此外,我们将此应用于计算某些空间图表的有理同伦类型的自同构群。
英文摘要
We extend Sullivan's rational homotopy theory by constructing geometrically and algebraically minimal models for diagrams of simply connected spaces over a class of finite indexing categories. Both classes classify rational diagram homotopy types, but their minimality conditions can differ. We also show that, in contrast to classical rational homotopy theory, H-diagrams need not split into products of Eilenberg--MacLane diagrams, and characterize the indexing categories for which every H-diagram admits such a splitting. Also we apply this to computation of automorphism groups of rational homotopy types of certain diagrams of spaces.
