Abstract
We construct a Banach Poisson–Lie group structure on the unitary group of a separable complex Hilbert space.
This research was partially supported by joint National Science Centre, Poland (number 2020/01/Y/ST1/00123) and Fonds zur Förderung der wissenschaftlichen Forschung, Austria (number I 5015-N) grant “Banach Poisson–Lie groups and integrable systems.”
