Several fields of mathematics have developed in total isolation, using their own 'undecipherable' coded languages. Mathematicians now present 'big algebras,' a two-way mathematical 'dictionary' ...

Abstract We prove that λ𝑔 ↦ 𝑒⁻𝑡|𝑔|𝑟 λ𝑔 defines a multiplier on the von Neuman algebra of hyperbolic groups with a complete bound ≃ 𝑟, for any 0 < 𝑡 < ∞, 1 < 𝑟 < ∞. In the proof we observe ...
