Precompact type properties – precompactness (=totally
precompactness), $\sigma$-precompactness, pre-Lindelöfness,
(=$\aleph_{0}$-boundedness), $\tau$-boundedness – belong to the
basic important invariants studied in the uniform topology.
The theory of these invariants is wide and continues to develop.
However, in a sense, the class of uniformly Menger spaces escaped
the attention of researchers.
Lj.D.R. Kočinac was the first who introduced and studied the
class of uniformly Menger spaces in [3, 4]. It
immediately follows from the definition that the class of uniformly
Menger spaces lies between the class of precompact uniform spaces
and the class of pre-Lindelöf uniform spaces. Therefore,
we expect it to have many good properties.
In this paper some important properties of the uniformly Menger
spaces are investigated. In particular, it is established that under
uniformly perfect mappings, the uniformly Menger property is
preserved both in the image and the preimage direction.
