Boundedness in uniform spaces and topological groups Jan Hejcman — 1959 Czechoslovak Mathematical Journal
On simple recognizing of bounded sets Jan Hejcman — 1997 Commentationes Mathematicae Universitatis Carolinae We characterize those uniform spaces and commutative topological groups the bounded subsets of which can be recognized by using only one uniformly continuous pseudometric.
