    Analysis

    This paper extends the classic rational angle bisection problem to higher dimensions and explores the rationality of incenters of simplices. It provides characterizations for when angle bisectors and incenters are rational, offering insights into geometric properties over fields. The generalization of the negative Pell's equation is a notable contribution.
