Mixed Hodge structures and Sullivan's minimal models of Sasakian manifolds
Hisashi Kasuya
We show that the Malcev Lie algebra of the fundamental group of a compact -dimensional Sasakian manifold with admits a quadratic presentation by using Morgan's bigra…
Cohomology computations of solvmanifolds with local coefficients
Hisashi Kasuya
Let be a simply connected solvable Lie group with a lattice and the nilradical of . For a complex valued representation such that the restriction $…
Minimal models, formality and hard Lefschetz properties of solvmanifolds with local systems
Hisashi Kasuya
For a simply connected solvable Lie group G with a cocompact discrete subgroup Γ, we consider the space of differential forms on the solvmanifold G/Γ with values in certain flat bu…
Algebraic hulls of solvable groups and exponential iterated integrals on solvmanifolds
Hisashi Kasuya
We represent the coordinate ring of algebraic hulls (which are generalizations of the Malcev completions of nilpotent groups for solvable groups) of solvmanifolds by using Mi…
