Irreducible decompositions of tensors via the Brauer algebra and applications to metric-affine gravity
Thomas Helpin
In the first part of this thesis, we make use of representation theory of groups and algebras to perform an irreducible decomposition of tensors in the context of metric-affine gra…

A metric-affine version of the Horndeski theory
Thomas Helpin, Mikhail S. Volkov
We study the metric-affine versions of scalar-tensor theories whose connection enters the action only algebraically. We show that the connection can be integrated out in this case,…
