Sequences of adjoints forEns-valued functors

open access: yesManuscripta Mathematica, 1980
A complete classification of full sequences of adjoint functors arising from arbitrary functors F∶A→Ens and faithful functors F∶A→Ens, respectively, is given.

A characterization of cellular motivic spectra

open access: yes, 2017
Let $ \alpha: \mathcal{C} \to \mathcal{D}$ be a symmetric monoidal functor from a stable presentable symmetric monoidal $\infty$-category $\mathcal{C} $ compactly generated by the tensorunit to a stable presentable symmetric monoidal $\infty$-category $ \

Topological functors and right adjoints

open access: yesGeneral Topology and its Applications, 1978
AbstractLet T:A → L be an (L, M)-topological functor and S:B → Y a faithful functor. Let F:L → Y and L:A → B be functors with a:FT → SL an epi natural transformation. We are concerned with the question of when L has a right adjoint given that F has a right adjoint. We give two characterizations of the existence of a right adjoint to L.

Adjoint functors and bar constructions

open access: yesAdvances in Mathematics, 1974
The notions of universal bundle, classifying space and bar construction are closely linked but not interchangeable. The relations between them are well understood in some contexts, less so in others. Our aim here is not to elucidate these relations but, merely, as a first step in such an elucidation, to clarify the notion of a bar construction.
