Abstract: A homology lens space is a smooth closed 3manif old M3with Hk(M3) = Hk(L(p, l)) for all k (p some nonnegative integer). When p= 1 M3is a homology 3sphere. It is an open question which of these homology lens spaces bound rational homology balls and of special interest which homology 3spheres bound contractible manifolds. In this note we answer this question for certain Seifert fibre spaces, each with three exceptional fibres. © 1981, University of California, Berkeley. All Rights Reserved.
