Steffen Oppermann

Steffen Oppermann is a Professor in the Algebra group at the Department of Mathematical Sciences, Norwegian University of Science and Technology (NTNU). His research focuses on representation theory, homological algebra, and cluster algebras. He holds an office in Room 844, Sentralbygg 2, and can be reached at steffen.oppermann@ntnu.no.

His work spans algebraic structures, including noncommutative algebra and derived categories, with notable contributions to Nakayama algebras, multi-parameter persistence modules, and Geigle-Lenzing spaces. Recent publications highlight advancements in triangulated categories, singularity theory, and categorical dualities.

Oppermann has advised doctoral student Torkil Utvik Stai, whose dissertation explored triangulated category constructions. He collaborates widely, with co-authors in algebra, topology, and computational mathematics. His research bridges pure algebraic theory with applications in data analysis and geometric frameworks.
