Superspace dynamics and perturbations around 'emptiness'
Superspace parametrized by gauge potentials instead of metric three-geometries is discussed in the context of the Ashtekar variables. Gauge-fixing conditions which lead to the natural geometricalExpand

On the invisible decays of the ϒ and J/Ψ resonances
We estimate the most important corrections to the branching ratios for the invisible decays of quarkonium states, arising from possible extensions of the Standard Model. Among the possibilitiesExpand

Gravitation as a gauge theory
We present gauge theories of gravitation based, respectively, on the general linear group GL(n, R) and its inhomogeneous extension IGL(n, R). (SO(n-1,1) and ISO(n-1,1) for torsion-free manifolds).Expand

On the Minimal Length Uncertainty Relation and the Foundations of String Theory
We review our work on the minimal length uncertainty relation as suggested by perturbative string theory. We discuss simple phenomenological implications of the minimal length uncertainty relationExpand

Exact solution of the harmonic oscillator in arbitrary dimensions with minimal length uncertainty relations
We determine the energy eigenvalues and eigenfunctions of the harmonic oscillator where the coordinates and momenta are assumed to obey the modified commutation relationsExpand

Effect of the minimal length uncertainty relation on the density of states and the cosmological constant problem
We investigate the effect of the minimal length uncertainty relation, motivated by perturbative string theory, on the density of states in momentum space. The relation is implemented through theExpand

Structure of the Vacuum and Neutron and Neutrino Oscillations
In a theory where the fermion numbers B and L are not conserved, the true ground state is a condensate of fermion pairs and antifermion pairs. Because of this, the usual analysis of fermionExpand

Nonlinear Gauge Fields and the Structure of Gravity and Supergravity Theories
By regarding the gauge fields which arise in theories based on nonlinear realizations of gauge symmetries as dynamical variables, we show that gravity, with or without matter, supergravity, andExpand
