On \(c\)-homotopies

, 1995
The author introduces an interesting notion of \(c\)-homotopy. The definition is the same as the usual one, only continuity is replaced by connectedness. Generalizing the Darboux property, the author calls a mapping to be connected if it sends connected sets onto connected sets. In the paper, the author shows that the \(c\)-homotopy has some reasonable

Analytical treatment of system of KdV equations by Homotopy Perturbation Method (HPM) and Homotopy Analysis Method (HAM)

, 2014
In this article the Homotopy Perturbation Method (HPM) and Homotopy Analysis Method (HAM) are applied to obtain analytic approximate solution to three system of nonlinear wave equations, namely two component evolutionary system of a homogeneous KdV ...

On the enumeration of cross-sections and unstable vector bundles [PDF]

This thesis is an attempt to generalise the methods of two papers [9], [11] by James and Thomas on enumeration problems. The first five sections consider the problem of enumerating the homotopy classes of cross-sections of a fibration F c X p B.

Homotopy limits and homotopy colimits of chain complexes

Journal of Pure and Applied Algebra
We give a formula for homotopy limits and homotopy colimits of diagrams of chain complexes using the cobar and bar constructions, also known as the Bousfield--Kan formula. Along the way, we show that the Bousfield--Kan formula computes homotopy colimits in any framed model category.
