Let G be a Lie group and let X be a space. It is believed that G and X are strongly related if there is a proper action of G on X, especially if the orbit space G\X is compact. The paper makes explicit one such relation, namely non-compact dimension. For a field k and a locally compact space X we call nc(X ; k) = inf {/: H'C(X ;k) ^ 0} the non-compact dimension of X (see §2). Let us fix a field...
