Regularization and Renormalization of Gauge Fields
A new regularization and renormalization procedure is presented. It is particularly well suited for the treatment of gauge theories. The method works for theories that were known to be renormalizableExpand

Confinement of quarks
Abstract A general introduction to the topological mechanism responsible for the absolute confinement of quarks inside hadronic bound states is given, including the effects of a finite instantonExpand

Naturalness, chiral symmetry, and spontaneous chiral symmetry breaking
A properly called “naturalness” is imposed on gauge theories. It is an order-of-magnitude restriction that must hold at all energy scales μ. To construct models with complete naturalness forExpand

Dimensional Reduction in Quantum Gravity
The requirement that physical phenomena associated with gravitational collapse should be duly reconciled with the postulates of quantum mechanics implies that at a Planckian scale our world is notExpand

Computation of the quantum effects due to a four-dimensional pseudoparticle
A detailed quantitative calculation is carried out of the tunneling process described by the Belavin-Polyakov-Schwarz-Tyupkin field configuration. A certain chiral symmetry is violated as aExpand

On the Phase Transition Towards Permanent Quark Confinement
In quantized gauge field theories one can introduce sets of operators that modify the gauge-topological structure of the fields but whose physical effect is essentially local. In 2 + 1 dimensionalExpand

One loop divergencies in the theory of gravitation
All one-loop divergencies of pure gravity and all those of gravitation interacting with a scalar particle are calculated. In the case of pure gravity, no physically relevant divergencies remain;Expand

A property of electric and magnetic flux in non-Abelian gauge theories
Abstract Pure non-Abelian gauge models with gauge group SU( N ) are considered in a box with periodic boundary conditions at various temperatures β −1 . Electric and magnetic flux are defined in aExpand

On the Quantum Structure of a Black Hole
The assumption is made that black holes should be subject to the same rules of quantum mechanics as ordinary elementary particles or composite systems. Although a complete theory for reconciling thisExpand

The gravitational shock wave of a massless particle
The (spherical) gravitational shock wave due to a massless particle moving at the speed of light along the horizon of the Schwarzchild black hole is obtained. Special cases of our procedure yieldExpand
