Lisbon, Portugal. 2007)We show an alternative construction of the first example of a simply-connected compact symplectic non-formal 8-manifold given in [6].We also give an alternative proof of its non-formality using higher order Massey products.engOn non-formality of a simply-connected symplectic 8-manifold.book parthttp://proceedings.aip.org/resource/2/apcpcs/1023/1/82_1?isAuthorized=noopen access514515.1GometryLie algebrasMatrix algebraGeometríaTopología1204 Geometría1210 Topología
