Abstract:
A compactum $X$ in Euclidean $4$-space ${E^4}$ is shown to be tame if its projection into ${E^3}$ is $1$-dimensional and if $\dim L \cap X \leqslant 0$ for each vertical line $L$ in ${E^4}$. An essential ingredient is the result due to J. L. Bryant and D. L. Sumners that a $1$-dimensional compactum in a $3$-dimensional hyperplane of ${E^4}$ is tame in ${E^4}$.References
