Abstract:

A positional pathology as described in the title is shown to occur in three-space. We construct an arcwise accessible point set $M$ such that each arc to $M$ is locally knotted at uncountably many points. In addition we give examples of connected, locally connected point sets $S$ and $T$ which are accessible at each point only by wild arcs and tame arcs respectively. The point set $M$ has countably many components, and each of these is a tame finite $2$-complex. Moreover ${E^3} - M$ is locally connected and arcwise connected.
