## Abstract We review some aspects of D‐instantons in intersecting D‐brane models. In particular, we present applications of the recently proposed instanton calculus to computations of charged matter superpotential couplings and corrections to the gauge kinetic function in the low energy effective

## Abstract We construct the most general non‐extremal spherically symmetric instanton solution of a gravity‐dilaton‐axion system with __SL__(2, __R__) symmetry, for arbitrary euclidean spacetime dimension __D__≥ 3. A subclass of these solutions describe completely regular wormhole geometries, whos
