论文摘要
我们在受Klein和Williams在交叉理论方面的工作启发的模型类别中为升力和扩展提供了阻碍。与代数拓扑的熟悉的障碍物相反，这种方法产生了一个不变的，在适当的维度和连通性假设的概括的存在中是完整的。
We give an obstruction for lifts and extensions in a model category inspired by Klein and Williams' work on intersection theory. In contrast to the familiar obstructions from algebraic topology, this approach produces a single invariant that is complete in the presences of the appropriate generalizations of dimension and connectivity assumptions.
