Erlend D. Børve

I am a mathematician, specialising in representation theory of algebras, tilting theory and generalisations, and related areas. Currently, I am a research assistant at the University of Cologne, funded by the DFG project Symplectic Structures in Geometry, Algebra and Dynamics. Towards the end of 2024, I will join the Algebraic Structures and Geometry Group at the University of Graz.

From June 2019 to June 2023, I was a PhD candidate at NTNU's Department of Mathematical Sciences, supervised by Aslak Buan. My PhD thesis is entitled Homotopical and geometric tools in representation theory. After my PhD, I spent a year as a CHARMS postdoctoral researcher at Institut Fourier.
