Understanding Differential Search Index for Text Retrieval

Xiaoyang Chen, Yanjiang Liu, Ben He +2

The Differentiable Search Index (DSI) is a novel information retrieval (IR) framework that utilizes a differentiable function to generate a sorted list of document identifiers in r…

Riemannian submersions from compact four manifolds

Xiaoyang Chen

We show that under certain conditions, a nontrivial Riemannian submersion from positively curved four manifolds does not exist. This gives a partial answer to a conjecture due to F…

Rigidity theorems for submetries in positive curvature

Xiaoyang Chen, Karsten Grove

We derive general structure and rigidity theorems for submetries , where is a Riemannian manifold with sectional curvature . When applied to a non-tri…
