[Abstract]
 The energy-momentum tensor in general relativity is the variational derivative
 of a given functional by the components of the metric tensor and there is an
 explicit formula. Yet this tensor in cosmology is calculated by some indirect
 method regardless of this formula.
 We propose a problem: how to find a functional with the given energy-momentum
 tensor.
