Abstract: Since the revolutionary ideas of Boltzmann well over a century ago, the rigorous derivation of kinetic transport equations for a macroscopic particle cloud remains one of the key challenges in mathematical physics. In these lectures I will describe recent progress in the case of the Lorentz gas, a dilute gas of point particles moving in an infinite array of scatterers, and describe the transport equations that emerge in the limit of small scatterer density. The lectures will introduce a nonexpert audience to the relevant techniques from dynamical systems, ergodic theory, number theory and mathematical physics.
