Description
Geometric methods have emerged in recent years, which allow for the expression of theories in a manifestly covariant form under field redefinitions through relating physical quantities to geometric structures.
Using jet bundles it is possible to express higher derivative terms in a geometric fashion, relating their couplings to the geometry of the bundle itself.
In this talk a brief introduction to jet bundles will be given as well as showcasing how the geometric objects may be treated as couplings which are invariant under field redefintions for terms with up to 4 derivatives.
