Titel: Counting extensions of division algebras over number fields (joint work with Fabian Gundlach)
Abstract: We present and explain the proof of results concerning the asymptotical density of discriminants of extensions of a given division algebra over a number field.
This is an extension of the question of the distribution of number fields to the case of non-commutative fields.
We explain what happens both in the case of "inner Galois extensions" (analogous to central simple algebras over a commutative field) and "outer Galois extensions" (analogous to ordinary Galois extensions of a commutative field).
