Resumen:
We provide the second known example of an extremally Ricci pinched closedG2-structure on a compact 7-manifold, by finding a lattice in the only unimodular solvableLie group admitting a left-invariant G2-structure. Furthermore, the Laplaciancoflow and its solitons are studied on a 6-parameter family of left-invariant coclosedG2-structures on this Lie group. In this way, we obtain a 4-parameter subfamily ofexpanding solitons. The family is locally pairwise non-equivalent.
