Given a simplicial pair (X,A), a simplicial complexY, and a map, doesfhave an extension toX? We show that for a fixedY, this question is algorithmically decidable for allX,A, andfifYhas the rational homotopy type of an H-space. As a corollary, many questions related to bundle structures over a finite complex are likely decidable. Conversely, for all otherY, the question is at least as hard as certain special cases of Hilbert’s tenth problem which are known or suspected to be undecidable.
