Query: New Method for Building Geodesic Lines in Riemann Geometry   New perspective form of equations for geodesic lines in Riemann Geometry was
found. This method is based on the use of differential forms in differential
equations as arguments of differentiation. At that, these forms do not have a
requirement of completeness, and that extends capabilities of equation
transformation, makes their writing very flexible and extend their scope of
application.
