Abstract:
Motivated by examples that appeared in the context of string theory?gauge theory duality, we consider corrections to supergravity backgrounds induced by higher derivative (R4+cdots, three dots, centered) terms in superstring effective action. We argue that supersymmetric solutions that solve BPS conditions at the leading (supergravity) order continue to satisfy a 1st order ?RG-type? system of equations with extra source terms encoding string (or M-theory) corrections. We illustrate this explicitly on the examples of R4 corrections to generalized resolved and deformed 6d conifolds and a class of non-compact 7d spaces with G2 holonomy. Both types of backgrounds get non-trivial modifications which we study in detail, stressing analogies between the two cases.
