Constructing near-embeddings of codimension one manifolds with countable dense singular sets (2008)
Repovš, D., Rosicki, W., Zastrow, A., Željko, M.
The purpose of this paper is to present, for all $n\ge 3$, very simple examples of continuous maps $f:M^{n-1} \to M^{n}$ from closed $(n-1)$-manifolds $M^{n-1}$ into closed $n$-manifold $M^n$ such...
On small homotopies of loops (2007)
Conner, G., Meilstrup, M., Repovš, D., Zastrow, A., Željko, M.
Two natural questions are answered in the negative: (1) If a space has the property that small nulhomotopic loops bound small nulhomotopies, then are loops which are limits of nulhomotopic loops...
