On intersection of simply connected sets in the plane

E. D. Tymchatyn, V. Valov

Several authors have recently attempted to show that the intersection of three simply connected subcontinua of the plane is simply connected provided it is non-empty and the inters…

Extension dimension and quasi-finite CW-complexes

Alex Karasev, Vesko Valov

We extend the definition of quasi-finite complexes by considering not necessarily countable complexes. We provide a characterization of quasi-finite complexes in terms of L-inverti…

Extraordinary dimension of maps

A. Chigogidze, V. Valov

We establish a characterization of the extraordinary dimension of perfect maps between metrizable spaces.

Extensional dimension and completion of maps

H. Murat Tuncali, E. D. Tymchatin, Vesko Valov

We prove that any closed map between metrizable spaces can be extended to a closed map between completely metrizable spaces with the same extensional dimension.

On Regularly Branched Maps

H. Murat Tuncali, Vesko Valov

Let $f : X \to Y$ be a perfect map between finite-dimensional metrizable spaces and $p \geq 1$ . It is shown that the space $C^{*} (X, R^{p})$ of all bounded maps from $X$ into $R^{p}$ …

On finite-dimensional maps

H. Murat Tuncali, Vesko Valov

Let $f : X \to Y$ be a perfect surjective map of metrizable spaces. It is shown that if $Y$ is a $C$ -space (resp., $dim Y \leq n$ and $dim f \leq m$ ), then the function space $C…
