Query: The collapsibility of some CAT(0) simplicial complexes of dimension 3   We study the collapsibility of finite simplicial complexes of dimension 3
endowed with a CAT(0) metric. Our main result states that, under an additional
hypothesis, finite simplicial 3-complexes endowed with a CAT(0) metric collapse
to a point through CAT(0) subspaces.
