In particular, we provide a complete characterization of invariant exact locally conformal closed G2-structures on simply connected Lie groups, and we present examples of compact manifolds with different types of locally conformal closed G2-structures.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttps://doi.org/10.3390/axioms7040090https://www.mdpi.com/2075-1680/7/4/90open accesslocally conformal closed G2-structurecoupled SU(3)-structureGeometría1204 Geometría
