The Principle of Covariance and the Hamiltonian Formulation of General Relativity
The implications of the general covariance principle for the establishment. The analysis is performed in the framework of the Einstein-Hilbert variational theory unconstrained. As a second step, the conditions of validity of the non...

Light-cone reduction of Witten’s open string field theory
We elucidate some exact relations between light-cone and covariant string field theories on the basis of the homological perturbation lemma for A ∞ . The covariant quartets: the latter generates the gauge symmetry and c...

Weyl gravity in covariant hamiltonian formalism
We find covariant canonical formalism for Weyl invariant gravity. We discuss constraint structure of this theory and its gauge fixed form and we argue that it corresponds to unimodular gravity....

Nambu-Poisson gauge theory
We generalize noncommutative gauge theory using Nambu-Poisson structures to obtain a new type of gauge theory with higher brackets and gauge fields. The approach is based on covariant coordinates and higher versions of the ...
