We will talk about our contribution to a large project with the goal of a
self-consistent numerical simulation of the evolution of the universe
beginning soon after the Big Bang and ending with the formation of
realistic stellar systems like the Milky Way. This is a multi-scale
problem of vast proportions. It requires the development of new
numerical methods that excel in accuracy, parallel scalability to the
processes relevant in galaxy formation. These numerical methods
themselves require the development of mathematical theory in order to
guarantee the above mentioned requirements. in this talk we shall focus
on our contribution to this effort. This is joint work among others with
Volker Springel.
