Uniqueness of sign-changing solutions to Trudinger's equation
* Today * Wednesday 11 March 2026, 10:15, M2 (M233)
We establish uniqueness for sign-changing solutions to Trudingers parabolic equation with time dependent $C^2$ Dirichlet boundary data.
This talk is based on my joint work with Peter Lindqvist and Mikko Parviainen; preprint available at arXiv:2602.04748.

p-Dirichlet structures, the resistance conjecture and energy image density property
* Today * Wednesday 11 March 2026, 11:15, M2 (M233)
We develop the axioms for p-dirichlet structures. This abstract framework unifies different approaches and leads to new results in conformal geometry. We show how two conjectures that were open for Dirichlet spaces can be shown to hold in this very general setting. In fact, the proofs came from thinking in this general framework. The talk includes joint work with Riku Anttila, Mathav Murugan and Lassi Rainio.

Deforming plane curves: a tale of computation and theory-building
* Monday 16 March 2026, 14:15, Y313
In this talk I discuss recent work on the deformation theory of plane curve singularities, with connections to algebraic combinatorics and knot theory. I will take the opportunity to use this project as a case study on the process of mathematical discovery. Technical details will be kept to a minimum, and the focus is instead on the interplay between computation and theory-building in research.
The talk is aimed at a general audience. Some familiarity with algebraic varieties will be helpful.

Algebraic complexity of tensors with three or more modes
Monday 30 March 2026, 14:15, M134
The algebraic complexity of bilinear maps and trilinear forms has been studied extensively, most notably in the context of complexity of matrix multiplication; for three-mode tensors, it is known that asymptotic circuit complexity and asymptotic rank coincide, but for tensors with more than three modes this asymptotic correspondence in general breaks down. This talk develops the basic correspondence for three modes as well as looks at recent work towards understanding the complexity of tensors with more than three modes. Based in part on joint work with Cornelius Brand, Radu Curticapean, Baitian Li, Ian Orzel, Tim Seppelt, and Jiaheng Wang (cf. https://arxiv.org/abs/2602.11975 ).
