Popis: This paper deals with the Lagrange vertical structure on the vertical space T V ( E ) endowed with a non null (1,1) tensor field F V satisfying ( F v 2 - a 2 )( F v 2 + a 2 )( F v 2 - b 2 )( F v 2 + b 2 ) = 0. In this paper, the authors have proved that if an almost product structure P on the tangent space of a 2 n -dimensional Lagrange manifold E is defined and the F ( ± a 2 ; ± b 2 )-structure on the vertical tangent space T V ( E ) is given, then it is possible to define the similar structure on the horizontal subspace T H ( E ) and also on T ( E ). In the next section, we have proved some theorems and have obtained conditions under which the distribution L and M are r -parallel, r ¯ anti half parallel when r = r ¯ . The last section is devoted to proving theorems on geodesics on the Lagrange manifold
