Metric bingles and tringles in H₃

In the 3-dimensional Berwald-Moor space are bingles and tringles constructed, as additive characteristic objects associated to couples and triples of unit vectors - practically lengths and areas on the unit sphere. In analogy with the spherical angles, we build two types of bingles (reciprocal and relative). It is shown that reciprocal bingles are norms in the space of exponential angles (in the bi-space H^{\flat}, which exponentially define the representation of poly-numbers. It is shown that the metric of this space coincides with the Berwald-Moor metric of the original space. The relative bingles are connected to the elements of the second bi-space (angles, in the space of angles) H^{2\flat} and allow to provide the doble-exponential representation of poly-numbers. The explicit formulas for relative bingles and tringles contain integrals, which cannot be expressed by means of elementary functions.
