Moduli space of bi-invariant metrics

Abstract

AbstractIn this work, we focus on describing the space of bi-invariant metrics in a Lie group up to isometry. i.e, metrics invariant under both left and right translations. We show that $$\mathfrak {BI}$$ BI , the moduli space of bi-invariant metrics, is an orbifold. Moreover, we give an explicit description of this orbifold, and of $$\mathfrak {EBI}$$ EBI , the space of bi-invariant metrics equivalent under isometries and scalar multiplies.
