The partially pre-ordered set of compactifications of Cp(X, Y)

open access: yesTopological Algebra and its Applications, 2015
In the set of compactifications of X we consider the partial pre-order defined by (W, h) ≤X (Z, g) if there is a continuous function f : Z ⇢ W, such that (f ∘ g)(x) = h(x) for every x ∈ X. Two elements (W, h) and (Z, g) of K(X) are equivalent, (W, h) ≡X (

Retracts of Ultrahomogeneous Structures in the Context of Katetov Functors

open access: yesDemonstratio Mathematica, 2015
In this paper, we characterize retracts of a wide class of Fraïssé limits using the tools developed in a recent paper by W. Kubis and the present author, which we refer to as Katetov functors.

Retracts in equiconnected spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
The object of this paper is to show that the concepts “retract” and “strong deformation retract” coincide for a subset of an equiconnected space. Also, we have a similar local version in a locally equiconnected space.

Fuzzy Retractions of Fuzzy Open Flat Robertson-Walker Space

open access: yesAdvances in Fuzzy Systems, 2013
Our aim in the present paper is to introduce and study new types of fuzzy retractions of fuzzy open flat Robertson-Walker model. New types of the fuzzy deformation retracts of model are obtained.

On a complete lattice of retracts of a free monoid generated by three elements [PDF]

open access: yesOpuscula Mathematica, 2008
We prove that the family of retracts of a free monoid generated by three elements, partially ordered with respect to the inclusion, is a complete lattice.
