H2n+1‐structures on odd‐dimensional projective spaces
Abstract
Abstract We prove that the Heisenberg group admits infinitely many inequivalent equivariant compactifications into for all . This result provides a non‐commutative analog of Hassett–Tschinkel's classical result, which shows that there exist infinitely many inequivalent equivariant compactifications of vector groups into projective spaces of dimension at least 6.
