Fuzzy cofibration and fuzzy Serre cofibration

Journal of Interdisciplinary Mathematics
In this paper, we investigate and present the idea of fuzzy cofibration and fuzzy Serre cofibration and we establish some characteristics and theorems of these concepts. In addition, to studying the fuzzy pullback of a fuzzy cofibration.

Equiconnectivity and cofibrations I

Manuscripta Mathematica, 1981
In this paper and its sequel, we generalize the notion of local equiconnectivity (LEC) given in [1] to that of h local equiconnectivity. We study these notions systematically using the theory of cofibrations and h cofibrations. Some classical results of locally equiconnected spaces are extended and generalized.

Finiteness of Total Cofibres

K-Theory, 2004
Let \(P\) be a polytope, \(F(P)\) the poset of its faces, including \(P\) and \(\emptyset\). Let \(\tilde F(P)\) denote the poset obtained from \(F(P)\) by adding a new element \(\infty\) bigger than any proper face but not comparable to \(P\). Given a diagram \(Y: F(P)\rightarrow Top_{*}\) the author studies the question of homotopy finiteness of the ...

Cofibrations of algebras

Annali di Matematica Pura ed Applicata, 1982
The chain complex of a twisted free product A*t, FK, is chain homotopy equivalent to a differential graded algebra, which is identified to be a confibration of algebras as defined by Quillen. Under certain connectivity conditions we obtain a long exact sequence connecting the homologies of A, K, and A*t FK. In particular we derive a long exact sequence
