Today was the final day of the 38th British Topology Meeting. It was fun! Great to see so many young people in the field and hear all the recent developments.

The first step in a project that is dear to my heart has now appeared on the arXiv (arxiv.org/abs/2509.04134). In it we develop a unified framework describing how different notions of symmetries of operator algebras are interlinked. We reveal interesting connections with homotopy theory as well.

G-kernels and Crossed Modules

We develop a unified framework based on topological crossed modules for various lifting obstructions for $Γ$-kernels. It allows us to identify actions, cocycle actions and $Γ$-kernels up to their natu...

Today is my birthday! Could you, please, share my art, it is the best gift an artist can get 💖

A close-up photo of me, a gremlin cat artist trying to pass as human 😸

An green/gold illustration of an elven maiden casting spell, with spirits gently surrounding her. Dragon Age inspired.

A portrait of a redhead aasimar with 4 spread wings and a blue eye on her forehead.

A poster-like illustration of Solas, Cass, and Fenris from Dragon Age. A ghostly, shining hand is touching Solas' chest (it's Lavellan!).
