On the number of terms in the Lovelock products
Xavier Lachaume
In this short note we wonder about the explicit expression of the expanding of the -th Lovelock product. We use the 1990's works of S. A. Fulling et al. on the symmetries of the…
On the concavity of a sum of elementary symmetric polynomials
Xavier Lachaume
We introduce a new problem on the elementary symmetric polynomials , stemming from the constraint equations of some modified gravity theory. For which coefficients is a linear…
The constraint equations of Lovelock gravity theories: a new -Yamabe problem
Xavier Lachaume
This paper is devoted to the study of the constraint equations of the Lovelock gravity theories. In the case of an empty, compact, conformally flat, time-symmetric, and space-like…
formalism of Lovelock gravity
Xavier Lachaume
In this note we perform the decomposition, or Arnowitt Deser Misner (ADM) formulation of Lovelock gravity theory. The hamiltonian form of Lovelock gravity was known si…
