The p-adic Borel regulator injectivity conjecture

Let kk be a number field and let pp be a rational prime. For every odd dimension 2m132m-1\geq3, consider the pp-adic Borel regulator map

K2m1(k)ZQpvpkv.K_{2m-1}(k)\otimes_{\mathbb Z}{\mathbb Q}_p\longrightarrow\bigoplus_{v\mid p}k_v.

The pp-adic Borel regulator injectivity conjecture. For every number field kk, every rational prime pp, and every odd dimension 2m132m-1\geq3, this map is injective.

The conjecture is expected to hold in the stated generality and is the number-theoretic conjecture to which the paper reduces questions about profinite invariance of hyperbolic volume and arithmeticity.
