On coshuffle comultiplication on configuration spaces

Byung Hee An

We introduce a coshuffle comultiplication on the singular chain complex of configuration spaces, and we show that this structure endows the configuration space with the structure o…

Hilbert polynomials of configuration spaces over graphs of circumference at most 1

Byung Hee An, Jang Soo Kim

The $k$ -configuration space $B_{k} Γ$ of a topological space $Γ$ is the space of sets of $k$ distinct points in $Γ$ . In this paper, we consider the case where $Γ$ is a graph o…

Quasi-isometry classification of certain graph $2$ -braid groups and its applications

Byung Hee An, Sangrok Oh

In \cite{Oh22}, the second author defined a complex of groups decomposition of the fundamental group of a finitely generated 2-dimensional special group, called an \emph{intersecti…
