The complex structures on Hn ( M , R ) are defined using the Hodge decomposition On Hp , q the Weil complex structure IW is multiplication by ip − q , while the Griffiths complex structure IG is multiplication by i if p > q and − i if p < q. Both these complex structures map Hn ( M , R ) into itself and so defined complex structures on it .
