Aug 5, 2018 at 21:19 comment added SashaKolpakov @IgorBelegradek: Thanks, Igor! Just in case, my question is related to this paper (arxiv.org/pdf/math/0007197.pdf) of Long and Reid about geometric cobordisms of hyperbolic 3-manifolds.
Aug 5, 2018 at 21:18 comment added SashaKolpakov @DannyRuberman: Thanks, Danny. Ok, I see: it might be hard, and I'm no real differential geometer. However, this question appears extremely interesting in the context of geometric cobordisms of hyperbolic 3-manifolds. If you're interested, I can write more by e-mail.
Aug 5, 2018 at 19:53 comment added Igor Belegradek Perhaps, the following will help "Index theorems on manifolds with straight ends" by Werner Ballmann, Jochen Bruning and Gilles Carron, mathematik.hu-berlin.de/~geomanal/bruening_publications/…. This is not on my fingertips so I cannot claim anything definite.
Aug 5, 2018 at 18:28 comment added Danny Ruberman This is a nice question, but probably very hard. A starting point might be a version of the eta-invariant for the Dirac operator (rather than signature operator) on an odd-dimensional hyperbolic manifold with a cusp, due to J. Park (Amer. J. Math. 127 (2005), no. 3, 493–534 or arxiv.org/abs/math/0111175.)
