Turaev-Viro invariant from the modular double of
Tianyue Liu, Shuang Ming, Xin Sun +2
We define a family of Turaev-Viro type invariants of hyperbolic -manifolds with totally geodesic boundary from the -symbols of the modular double of $\mathrm U_{q}\mathfrak{…

Toric Einstein 4-manifolds with nonnegative sectional curvature
Tianyue Liu
We prove that -invariant Einstein metrics with non-negative sectional curvature on a four-manifold are locally symmetric.
