Breuning's local equivariant epsilon constant conjecture

Let $N/K$ be a Galois extension of local number fields, let $G$ be its Galois group, and let $R_{N/K}$ be Breuning's element of $K_0(\mathbb Z_p[G],\mathbb Q_p)$ incorporating local epsilon constants and algebraic invariants associated with $N/K$. Breuning's local equivariant epsilon constant conjecture. One has

$$R_{N/K}=0$$

in $K_0(\mathbb Z_p[G],\mathbb Q_p)$. This is a local formulation of the equivariant epsilon constant problem and is presented as an independent conjecture underlying the local approach to known cases of the global conjecture. The supplied text does not establish the conjecture in general.
