We develop a possibilistic semantic formalism for quantum phenomena from an operational perspective. This system is based on Chu duality between preparation processes and yes/no tests, the target space being three-valued set equipped with informational interpretation. A basic of axioms introduced states. suffices to constrain states be projective domain. The subset pure then characterized withi...

In this work we develop a perturbative formalism for the treatment of Lovelock theories of gravity. We consider in detail D-dimensional models in Lovelock gravity with an induced metric given by the product of the metrics of two maximally symmetric spaces. We first explicitly obtain the Lovelock action, Hamiltonian constraint, gravitational momenta, and dynamical equations for this type of mini...

Geometrical diagnostic methods were often applied to distinguish the gravitational models. But it is scarce investigate differences between different formalisms of modified theories (e.g. metric formalism and Palatini formalism). In this paper, we discriminate theory with by using geometrical methods. For a considered gravity f(R) or GBD theory), can see that difference two remarkable according...
