Fiberwise homotopy

WebJun 2, 2011 · We give a description of homotopy invariants of spaces in terms of minimal models (Theorem 1.0.2). The minimal model in this context behaves much like the Sullivan’s minimal model. We also provide some examples. We prove an equivalence between fiberwise rationalizations (Bousfield and Kan in Lecture Notes in Mathematics, vol 304. WebAug 1, 2024 · This is false; as demonstrated by the example below, rational homotopy obstructions may still crop up in the interaction between base and fiber. The correct fiberwise statement should relate to rational fiberwise H-spaces, as discussed for example in . However, such a result presents technical difficulties which will require significant new ...
