Query: Three Lectures on the Physics of Small x and High Gluon Density   In these lectures, I shall discuss small x physics and the consequences of
high gluon density which arises as x decreases. I argue that an understanding
of this problem would lead to knowledge of the high energy asymptotics of
hadronic processes. The high gluon density should allow a first principles
computation of these asymptotics from QCD.
