Title
Theoretical aspects of HERA physics
Abstract
I discuss the theoretical underpinnings for the extraordinary success
of perturbative QCD in the description of HERA data.
In particular, I examine recent progress in the understanding of
perturbative QCD at small x. I explain the relation between evolution
equations in Q2 and x, and how they can be used for simultaneous
resummation of the relevant large logs at HERA. I show that while the
HERA data can be understood within our current knolwedge of the
perturbative expansion of QCD, they pose stringent constraints on the
perturbatively unacessible behaviour of QCD in the Regge limit.
