This work is mainly devoted to constructing a multisymplectic description of Lovelock’s gravity, which is an extension of General Relativity. We establish the Griffiths variational problem for the Lovelock Lagrangian, ...

We study the conditions of integrability when the boundary terms are considered in the variation of the geometric contribution of the Einstein–Hilbert action. We explore the emergent physical dynamics that is obtained when ...

Dual-helicity eigenspinors of the charge conjugation operator (ELKO spinor fields) belong - together with Majorana spinor fields - to a wider class of spinor fields, the so-called flagpole spinor fields, corresponding to ...

In the first part of this work we show the decoupling (up to contact terms) of redundant degrees of freedom which appear in the covariant description of spin-two massive particles in D=2+1. We make use of a master action ...

In this paper we describe 4-dimensional gravity coupled to scalar and Maxwell fields by the Einstein-Katz action, that is, the covariant version of the “Gamma-Gamma −Gamma-Gamma” part of the Hilbert action supplemented by ...
