In general coordinate invariant gravity theories whose Lagrangians contain arbitrarily high order derivative fields, the Noether currents for the global translation and for the Nakanishi’s IOSp(8|8) choral symmetry containing the BRS symmetry as its member are constructed. We generally show that for each of these Noether currents, a suitable linear combination of equations of motion can be brought into the form of a Maxwell-type field equation possessing the Noether current as its source term.

Quantum scale invariant gravity in the de Donder gauge

We perform the manifestly covariant quantization of a scale invariant gravity with a scalar field, which is equivalent to the well-known Brans-Dicke gravity via a field redefinition of the scalar

We perform a manifestly covariant quantization of a Weyl invariant, i.e., a locally scale invariant, scalar-tensor gravity in the extended de Donder gauge condition (or harmonic gauge condition) for



Renormalization of Higher Derivative Quantum Gravity

Gravitational actions which include terms quadratic in the curvature tensor are renormalizable. The necessary Slavnov identities are derived from Becchi-Rouet-Stora (BRS) transformations of the

The problem of motion in gauge theories of gravity

In this article we consider the problem to what extent the motion of gauge-charged matter that generates the gravitational field can be arbitrary, as well as what equations are superimposed on the

Aspects of quadratic gravity

We discuss quadratic gravity where terms quadratic in the curvature tensor are included in the action. After reviewing the corresponding field equations, we analyze in detail the physical propagating

Local Covariant Operator Formalism of Non-Abelian Gauge Theories and Quark Confinement Problem

A manifestly covariant and local canonical operator formalism of non-Abelian gauge theories is presented in its full detail. This formalism, applicable to Yang-Mills theories as well as to gravity,

Dynamical Gauge Bosons and Hidden Local Symmetries

Various theoretical problems concerning dynamical generation of composite gauge bosons are discussed. In particular we clarify the general mechanism how massless gauge bosons of hidden local symmetry

The Asymptotic Safety Scenario in Quantum Gravity

Criteria for a continuum limit are formulated and the notion of a background geometry self-consistently determined by the quantum dynamics is presented and self-contained appendices provide prerequisites on the background effective action, the effective average action, and their respective renormalization flows.

Quadratic Gravity

Adding terms quadratic in the curvature to the Einstein-Hilbert action renders gravity renormalizable. This property is preserved in the presence of the most general renormalizable couplings with

It is shown that, nevertheless, agravity can be a complete theory valid up to infinite energy and a useful equivalence between agravity and conformal gravity plus two extra conformally coupled scalars is shown.
