The gravitational energy-momentum pseudo-tensor of Higher-Order Theories of Gravity

S. Capozziello, M. Capriolo, M. Transirico

We derive the gravitational energy momentum tensor ${\tau }_{\alpha }^{\eta }$ for a general Lagrangian of any order $L=L\left(g_{μν}, g_{μν,i_{1}}, g_{μν,i_{1}i_{2}},g_{μν,i_{1}i_{2}i_{3}},\cdots, g_…
