Higher dimensional Taub-Bolt solutions and the entropy of non compact manifolds

We discuss the action of a circle isometry group on non compact Euclidean Einstein manifolds. We discuss approaches to a decomposition of the action and entropy for non compact manifolds in terms of the characteristics of the orbit space of a suitable isometry. There is entropy associated with non trivial cohomology of the orbit space of the isometry, and we consider a class of non compact solutions for which such contributions do not vanish. To obtain suitable solutions we generalise the Bais-Batenburg construction of higher dimensional Taub-Nut type solutions to obtain the corresponding bolt solutions. We consider the generalisations to non compact solutions of gravity coupled to scalar and gauge fields.
