## Abstract We characterize and provide examples of the analytic selfβmaps of the unit disc, which induce isometric comβposition operators on the space __BMOA__ equipped with a MΓΆbius invariant __H__^2^ norm (Β© 2010 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)

An expression is found for the L 2 -index of a Dirac operator coupled to a connection on a U n vector bundle over S 1 \_R 3 . Boundary conditions for the connection are given which ensure the coupled Dirac operator Fredholm. Callias' index theorem is used to calculate the index when the connection i
