Let $X$ be a noncompact generalized continuum. Let $T$ be an infinite tree and let … be a proper embedding. Assume that the induced map on end spaces … is injective. Existence of a…

Let $X$ be a noncompact, metrizable generalized continuum. An infinite rooted tree is an infinite tree with a distinguished root, and a proper embedding is a topological embedding…

A tree is a locally finite, acyclic simplicial $1$-complex, and a baseray is the ray-based object used in the results of Section; the source's preceding discussion concerns existen…

Let $M$ and $N$ be open, one-ended manifolds of dimension greater than $3$. Their end sum is formed using a proper ray in each manifold, and the resulting manifold may depend on th…
