On Subspaces of an Almost φ-Lagrange Space

الملخص EN

We discuss the subspaces of an almost φ-Lagrange space (APL space in short).

We obtain the induced nonlinear connection, coefficients of coupling, coefficients of induced tangent and induced normal connections, the Gauss-Weingarten formulae, and the Gauss-Codazzi equations for a subspace of an APL-space.

Some consequences of the Gauss-Weingarten formulae have also been discussed.
