Contribution
It introduces and analyzes two functorial prolongation methods for functional bundles, establishing the preservation of vector field brackets and providing new insights into Weil bundles.
Findings
Proves bracket preservation in both prolongation cases
Develops new results on finite dimensional Weil bundles
Enhances understanding of functorial properties in fibered manifolds
Abstract
We discuss two kinds of functorial prolongations of the functional bundle of all smooth maps between the fibers over the same base point of two fibered manifolds over the same base. We study the prolongation of vector fields in both cases and we prove that the bracket is preserved. Our proof is based on several new results concerning the finite dimensional Weil bundles.
