“…On the less usual topic of double vector bundles which is the core of the present paper, the above references [4] and [5] only mention the double tangent space TTdouble-struckM$TT{\mathbb {M}}$ of a manifold M${\mathbb {M}}$. A general presentation of double vector bundles is provided for example in [6] but the reader of the paper may omit the general theory of double vector bundles.…”

“…In [2], a new class of g-natural metrics was introduced on the cotangent bundle, to which the Cheeger-Gromoll metric belongs. A similar approach was implemented by K. Niedzialomski [11], applied to the bundle of linear frames.…”
