On balanced Hermitian threefolds with parallel Bismut torsion

Differential Geometry 2025-10-14 v2

Abstract

We continue our study on Hermitian manifolds that are {\em Bismut torsion parallel,} or {\em BTP} for brevity, which means that the Bismut connection has parallel torsion tensor. For n3n\geq 3, BTP metrics can be balanced (and non-K\"ahler). In this paper, we give a detailed description to characterize all compact, balanced BTP threefolds.
