This is achieved through a generalization of the latter, which in addition allows us to provide a coeffective version of the filtered cohomologies introduced by Tsai, Tseng and Yau. We construct closed (simply connected) manifolds endowed with a family of symplectic forms ¿t such that the dimensions of these symplectic cohomology groups vary with respect to t. A complete study of these cohomologies is given for 6-dimensional symplectic nilmanifolds, and concrete examples with special cohomological properties are obtained on an 8-dimensional solvmanifold and on 2-step nilmanifolds in higher dimensions.2019http://zaguan.unizar.es/record/8650610.1007/s10231-018-0819-8http://zaguan.unizar.es/record/86506oai:zaguan.unizar.es:86506info:eu-repo/grantAgreement/ES/DGA/E22-17Rinfo:eu-repo/grantAgreement/ES/MINECO/MTM2017-85649-PAnnali di Matematica Pura ed Applicata 198 (2019), 1351–1380All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
