<b>Abstract: </b>You might've heard
about various mathematical
properties of scattering amplitudes
such as analyticity, sheets, branch
cuts, discontinuities, etc. What
does it all mean? In these lectures,
we'll take a guided tour through
simple scattering problems that will
allow us to directly trace such
properties back to physics. We'll
learn how different analytic
features of the S-matrix are really
consequences of causality, locality
of interactions, unitary
propagation, and so on.<br>
<br>
This talk is a part of a series of
lectures aimed at graduate students.
The first one will focus on the link
between analyticity, causality, and
dispersive properties of media.<br>
