We consider a gravitational theory with an additional non-minimal coupling between baryonic matter fields and geometry. The is second order in the energy momentum tensor can be seen as generalization of energy-momentum squared gravity model. will add constraint through Lagrange multiplier to ensure conservation tensor. Background cosmological implications together its dynamical system analysis ...

A bstract We construct a non-relativistic limit of ten-dimensional $$ \mathcal{N} N = 1 supergravity from the point view symmetries, action, and equations motion. This can only be realized in supersymmetric way provided we impose by hand set geometric constraints, invariant under all symmetries theory, that d...
