Query: Finsleroid--Relativistic Space Endowed With Scalar Product   When a single time-like vector is distinguished geometrically to present the
only preferred direction in extending the pseudoeuclidean geometry, the
hyperboloid may not be regarded as an exact carrier of the unit-vector image.
So under respective conditions one may expect that some time-assymetric figure
should be substituted with the hyperboloid. To this end we shall use the
pseudo-Finsleroid. The spatial-rotational invariance (the P-parity) is
retained. The constant negative curvature is the fundamental property of the
pseudo-Finsleroid surface. The present paper develops the approach in the
direction of evidencing the concepts of angle, scalar product, and geodesics.
In Appendices we shortly outline the basic aspects that stem from the choice of
the Finsleroid-relativistic metric functions.
