Gromov's Simplicial Volume Vanishing Conjecture for Positive Scalar Curvature and Fundamental Group Decay

Qiaochu Ma, Guoliang Yu

The paper proves Gromov’s conjecture that closed oriented manifolds with positive scalar curvature have zero simplicial volume, assuming a mild decay condition on the fundamental g…

Gromov's dihedral rigidity conjecture in dimension three

Jinmin Wang, Zhizhang Xie, Guoliang Yu

In this article, we present a self-contained proof of Gromov's dihedral rigidity conjecture on scalar curvature in the three-dimensional case. The proof avoids many of the technica…

Small scale index theory, scalar curvature, and Gromov's simplicial norms

Qiaochu Ma, Guoliang Yu

In this article, we study the topological complexity of manifolds with a lower scalar curvature bound. We introduce a small scale index theorem to establish an upper bound for Grom…

Strong relative Novikov conjecture for coarsely embeddable groups

Geng Tian, Zhizhang Xie, Guoliang Yu

In this article, we prove a strong relative Novikov conjecture for any pair of groups that are coarsely embeddable into Hilbert space.

Hilbert-Hadamard spaces and the equivariant coarse Novikov conjecture

Liang Guo, Qin Wang, Jianchao Wu +1

The equivariant coarse Novikov conjectures stand among a handful profound -theoretic conjectures in noncommutative geometry. Motivated by the quest to verify Novikov-type conjec…

-coarse Baum-Connes conjecture for -coarse embeddable spaces

Jinmin Wang, Zhizhang Xie, Guoliang Yu +1

We prove an -version of the coarse Baum-Connes conjecture for spaces that coarsely embedds into -spaces for any and in .
