Abstract

We study G 2 $$ G_{2} $$ -manifolds obtained from circle bundles over symplectic SU ( 3 ) $$ \operatorname {SU}(3) $$ -manifolds with T 2 $$ T^{2} $$ -symmetry. When the geometry is multi-Hamiltonian, we show how the compact part of the resulting multi-moment graph for the G 2 $$ G_{2} $$ -structure may obtained cohomologically from the base. The lifting procedure is illustrated in the context of toric geometry.
