A b$b$‐symplectic slice theorem

Abstract

In this article, motivated by the study of symplectic structures on manifolds with boundary and the systematic study of b $b$ -symplectic manifolds started in Guillemin, Miranda, and Pires Adv. Math. 264 (2014), 864–896, we prove a slice theorem for Lie group actions on b $b$ -symplectic manifolds.
