Flat Hermitian Lie algebras are Kähler
Dongmei Zhang, Fangyang Zheng
In 1976, Milnor classified all Lie groups admitting a flat left-invariant metric. They form a special type of unimodular 2-step solvable groups. Considering Lie groups with Hermiti…

Chern flat manifolds that are torsion-critical
Dongmei Zhang, Fangyang Zheng
In our previous work, we introduced a special type of Hermitian metrics called {\em torsion-critical,} which are non-Kähler critical points of the -norm of Chern torsion over…
