Fibrations That are Cofibrations. II [PDF]
Proceedings of the American Mathematical Society, 1989 We show that fibrations that are cofibrations can be described quite explicitly (in terms of localization) when the total space of the fibration is nilpotent and that, in the absence of nilpotency, no such simple characterization exists.

Quasicategories of Frames of Cofibration Categories [PDF]
Applied Categorical Structures, 2015 The authors show that the quasicategory of frames of a cofibration category, introduced by the second-named author, is equivalent to its simplicial localization. In particular, it follows that given a model category, the quasicategories of frames associated to its underlying cofibration and fibration categories are equivalent. In the very last section,

Mixed Approximate(Hurewicz) Cofibration
Journal of Wasit for Science and Medicine, 2022 In this papers we study a new concept namely (M-approximate cofibration) Mixed Approximate Cofibration and(M-approximate Hurewicz cofibration) Mixed approximate Hurewicz cofibration. Most of theorem which are valid for cofibration will also be valid for (M- cofibration); the others will be valid if we add extra conditions .

On the Left Properness of the Model Category of Permutative Categories
Axioms, 2023 In this paper, we introduce a notion of free cofibrations of permutative categories. We show that each cofibration of permutative categories is a retract of a free cofibration.

Correspondences and stable homotopy theory
Transactions of the London Mathematical Society, Volume 10, Issue 1, Page 124-155, December 2023., 2023 Abstract A general method of producing correspondences and spectral categories out of symmetric ring objects in general categories is given. As an application, stable homotopy theory of spectra SH$SH$ is recovered from modules over a commutative symmetric ring spectrum defined in terms of framed correspondences over an algebraically closed field ...
