Proposition 1.3.

Fix a basis (e1′,…,er′)(e^{\prime}_{1},\ldots,e^{\prime}_{r}) of VV. For any α∈(0,1)\alpha\in(0,1), there exists an α\alpha-orthogonal basis (e1,…,er)(e_{1},\ldots,e_{r}) of VV with respect to ‖.‖\|\raisebox{1.72218pt}{.}\| such that (e1,…,er)(e_{1},\ldots,e_{r}) is compatible with (e1′,…,er′)(e^{\prime}_{1},\ldots,e^{\prime}_{r}). Moreover, if the absolute value |.||\raisebox{1.72218pt}{.}| is discrete, then there exists an orthogonal basis (e1,…,er)(e_{1},\ldots,e_{r}) of VV compatible with (e1′,…,er′)(e^{\prime}_{1},\ldots,e^{\prime}_{r}).
