A note on solvable Lie groups without lattices and the Felix-Thomas models of fibrations
Aleksy Tralle
In this paper we show that a certain solvable Lie group constructed in a paper by Benson and Gordon has no lattices. This result answers (in the negative way) a question posed by s…

On symplectic manifolds with aspherical symplectic form
Yuli Rudyak, Aleksy Tralle
We consider closed symplectically aspherical manifolds, i.e. closed symplectic manifolds satisfying the condition . Rudyak and Oprea [RO] remarked that such…

On Thom spaces, Massey products and non-formal symplectic manifolds
Yuli Rudyak, Aleksy Tralle
In this work we analyze the behavior of Massey products of closed manifolds under the blow-up construction. The results obtained in the article are applied to the problem of constr…
