This set of lecture notes presents a pedantic derivation of the connection between the A -genus of spacetime's loop space and the genus one partition function of the N=1/2 sigma model. It concludes with some remarks on possible generalizations of the A -genus which follow naturally from the `stringy' point-of-view but have yet to be explored mathematically. This set of lecture notes is geared towards a mathematical audience unfamiliar with the N=1/2 sigma model.
