Cohomological beta function
Oleksandr Gamayun, Maxim Gritskov, Andrey Losev
We propose a cohomological approach to computing the conformal anomaly. Using the example of current-current deformations of two-dimensional conformal field theories, we reproduce…

Perturbative anomalies in quantum mechanics
Maxim Gritskov, Andrey Losev, Saveliy Timchenko
In this work, we propose a cohomological approach to studying perturbative anomalies in quantum mechanics. The Hamiltonian together with the symmetry generator …
