Steffen Oppermann

Steffen Oppermann is a Professor in the Department of Mathematical Sciences at the Norwegian University of Science and Technology (NTNU). His research focuses on advanced areas of algebra, including representation theory, homological algebra, cluster algebras, and triangulated categories. His work often intersects with algebraic geometry and category theory, particularly in studies of derived categories, quiver representations, and noncommutative algebraic structures. Key contributions include explorations of Nakayama algebras, silting mutation, and multi-parameter persistence modules in computational topology.

Oppermann has published extensively in top-tier journals such as Advances in Mathematics, Journal of Algebra, and Compositio Mathematica. His recent work bridges algebraic structures with topological data analysis, exemplified by studies on bottleneck stability in multi-parameter persistence. Collaborations with researchers like Magnus Botnan and Osamu Iyama highlight his interdisciplinary approach.

Teaching responsibilities include courses on representation theory (MA8205) and algebraic geometry (MA8203). His research has been supported through various academic networks and institutional grants at NTNU.
