CLAIR-Fin: An Adversarial Multi-Agent Framework for Claim-Level Verification and Adaptive Debate in Cross-Modal Financial QA
Fatema Tuj Johora Faria, Mukaffi Bin Moin, Jubayer Al Mahmud +2
Existing defenses against hallucination in retrieval-augmented and multi-agent pipelines remain partial: evidence is trusted despite modality disagreement, debate verifies an aggre…
Strict comparison holds in the uniform Roe algebra of a discrete amenable group
George A. Elliott, Chun Guang Li, Zhuang Niu +1
Let be a countable discrete amenable group, and let . It is shown that if are positive elements such that $$\mathrm{…
Villadsen algebras are singly generated
Chun Guang Li, Zhuang Niu, Vincent M. Ruzicka
We show that Villadsen algebras, which are not Z-stable, are singly generated. More generally, we show that any simple unital AH algebra with diagonal maps is singly generated.
On the small boundary property and -absorption
George A. Elliott, Zhuang Niu
We introduce Property (C) for a unital commutative sub-C*-algebra of a unital C*-algebra , which is a version of the relative comparison property using almost normalizers. I…
On the small boundary property, -absorption, and Bauer simplexes
George A. Elliott, Zhuang Niu
Let be a compact metrizable space, and let be a closed set of Borel probability measures on . We study the small boundary property of the pair . In particular,…
