Abstract
We generalize Bousfield–Friedlander’s Theorem and Hirschhorn’s Localization Theorem to settings where the hypotheses are not satisfied at the expense of obtaining semi-model categories instead of model categories. We use such results to answer, in the world of semi-model categories, an open problem posed by May–Ponto about the existence of Bousfield localizations for Hurewicz and mixed type model structures (on spaces and chain complexes). We also provide new applications that were not available before, e.g. stabilization of non-cofibrantly generated model structures or applications to mathematical physics.
