Another approach to parametric Bing and Krasinkiewicz maps
Vesko Valov
Using a factorization theorem due to Pasynkov we provide a short proof of the existence and density of parametric Bing and Krasinkiewicz maps. In particular, the following corollar…

Maps with dimensionally restricted fibers
Vesko Valov
We prove that if is a closed surjective map between metric spaces such that every fiber belongs to a class of space , then there exists an $…
