Networks and farsighted stability [PDF]
, 2001 We make two main contributions to the theory of economic and social network formation. First, we introduce the notion of a network formation network or a supernetwork.

Field Decomposition and the Ground State Structure of SU(2) Yang-Mills Theory
, 2002 We compute the effective potential of SU(2) Yang-Mills theory using the background field method and the Faddeev-Niemi decomposition of the gauge fields.

The twisted gradient flow coupling at one loop
, 2019 We compute the one-loop running of the $SU(N)$ 't Hooft coupling in a finite volume gradient flow scheme using twisted boundary conditions. The coupling is defined in terms of the energy density of the gradient flow fields at a scale $\tilde{l}$ given by

EFFECTS OF SHADOWING IN DOUBLE POMERON EXCHANGE PROCESSES
, 1995 The effects of shadowing in double Pomeron exchange processes are investigated within an eikonal approach with a Gaussian input. Damping factors due to screening are calculated for this process and compared with the factors obtained for total, elastic ...
