For my research I want to somehow generalize well known results about the Proj of a graded ring to arbitrary gradings by finitely generated abelian groups. This leads to the notion of multihomogeneous spectra, first introduced by Brenner/Schröer in 2007.
It turns out that the grading has major influence on the constructed spectra, in particular on the separatedness.
My final goal is to find a correspondence of the multigrading of a polynomial ring and the separatedness of the corresponding toric prevariety.


I prepare(d) the exercise classes for the following lectures

Winter Term 2019/2020Algebraic Geometry I
Elementarmathematik I
Summer Term 2020Algebraic Geometry II
Elementarmathematik II
Winter Term 2020/2021Algebraic Geometry III
Linear Algebra I
Summer Term 2021Linear Algebra II
Winter Term 2021/2022Algebra
Summer Term 2022Commutative Algebra
Elementarmathematik II

My supervisor Prof. Alex Küronya and me have written a textbook on elementary math (corresponding to the lecture series `Elementarmathematik') that is going to be published by Springer in the course of 2023.
