Abstrakt: The topological Tverberg theorem states that any continuous map of a (d+1)(r−1)$(d+1)(r-1)$‐simplex into the Euclidean d$d$‐space maps some points from r$r$ pairwise disjoint faces of the simplex to the same point whenever r$r$ is a prime power. We substantially generalize this theorem to continuous maps of certain CW complexes, including simplicial ((d+1)(r−1)−1)$((d+1)(r-1)-1)$‐spheres, into the Euclidean d$d$‐space. We also discuss the atomicity of the Tverberg property. [ABSTRACT FROM AUTHOR]
