Abstract: 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. We will illustrate our lecture by numerical simulations of the evolution of the universe. This is joint work among others with Volker Springel.

Speaker’s Bio: Christian Klingenberg received his PhD in 1983 from the Courant Institute of Mathematical Sciences, New York University, under the advisement of Cathleen Morawetz. He completed his postdoc position from 1983-1985 at the Courant Institute with James Glimm. He was an assistant professor from 1985 - 1994 at Heidelberg University. He has been a professor since 1995 at the Würzburg University in the mathematics department. He has had many collaborations with astrophysics.
