Let $D_2$ be the Bloch–Wigner dilogarithm, and consider its values $D_2(z)$ at algebraic arguments $z$. Zagier's conjecture. Every rational linear relation among these values is a…

Let $\mathcal B(k)$ denote the Bloch group of a field $k$, and let $\overline{\mathbb Q}$ be the field of algebraic numbers. The natural map … is known to be injective. Bloch rigid…

Let $\mathcal B(\mathbb C)$ be the Bloch group, defined as the kernel of the complex Dehn invariant, and let … be the Bloch regulator map. Bloch regulator injectivity conjecture. T…
