Lotte Hollands is widely recognized for her contributions to the mathematics of supersymmetric quantum field theories, and topological string theory. She will visit the CRC from May 13th to 23rd, 2026.
Together with Andy Neitzke she has in particular developed the abelianization program as a geometric tool allowing one to encode nonperturbative effects of supersymmetric gauge theories in terms of simpler, abelian structures encoded in certain graphs on Riemann surfaces. Mathematically, abelianization defines canonical coordinate charts for the moduli spaces of flat connections on Riemann surfaces, a ubiquitous mathematical object appearing in many part of mathematics and mathematical physics.
Lotte Hollands is a professor in Mathematics at Heriot-Watt University and the Maxwell Institute in Edinburgh.
She received the Anne Bennett Prize from the London Mathematical Society for outstanding research at the interface of quantum theory and geometry, as well as outreach efforts.
