摘要：

The arguments are given that exotic smooth R(4)'s can be considered as the natural counterpart for geometry of quantum gravity in some limits. This follows from the relations of these exotics to Z(2) orientifolds of WZW models on SU(2), abelian gerbes on S(3), generalized Hitchin's-Gualtieri structures as well gerbes on some orbifolds. Non-standard smoothings of R(4) seem to carry also quantum information about spacetime and gravity. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
