**Abstract: **The projection formula is one of the most basic results of
representation theory. In this lecture, we shall see how rephrasing it
in a different language allows us to predict the form of the celebrated
Riemann-Roch theorem. If time permits, we will elaborate on the
relationship to Hochschild homology and generalized notions of trace.
The lecture will be somewhat informal, and its primary goal will be
trying to convey some ideas that emerged in algebraic geometry, often
with origin in topology, in the last few decades.

Vljudno vabljeni!
