### Catalogue data

Abstract | In addition to its mathematical content, this seminar shall provide an insight into what is usually hidden away from the reader of an article. |

Objective | The gradual development from an initial wish to make progress on a certain topic towards a published article is usually hidden away in the final text. The idea of this seminar is to have a look at the two author paper "Power sums of Coxeter exponents" (Advances in Mathematics 231 (2012), 1291-1307), that arose entirely by means of email correspondence, and to make accessible some excerpts from this correspondence in order to gain some insight into how the article evolved. This might be instructive in particular with regard to the students' own research ambitions. |

Literature | J. Burns, R. Suter: Power sums of Coxeter exponents, Adv. Math. 231 (2012), 1291-1307. Link |

Prerequisites / Notice | No prior knowledge of Coxeter exponents is required because some relevant stuff about Coxeter groups and root systems shall be explained in an early seminar talk. |
