Relative second bounded cohomology of free groups

Cristina Pagliantini, Pascal Rolli

This paper is devoted to the computation of the space $H_{b}^{2} (Γ, H; R)$ , where $Γ$ is a free group of finite rank $n \geq 2$ and $H$ is a subgroup of finite rank. More precise…

Split quasicocycles

Pascal Rolli

Let E be a linear isometric representation of a group Γ. In this paper we construct and study a family of quasicocycles Γ-> E that arise from splittings Γ= A * B. Under certain ass…

Quasi-morphisms on Free Groups

Pascal Rolli

Let F be the free group over a set of two or more generators. R. Brooks constructed an infinite family of quasi-morphisms on F such that an infinite subfamily gives rise to indepen…
