Superluminal electromagnetic fields of dyons are described in T^{4}- space and Quaternion formulation of various quantum equations is derived. It is shown that on passing from subluminal to superluminal realm via quaternion the theory of dyons becomes the... see more

Afin d'expliquer les performances exceptionnelles (croissance soutenue, faible niveau de chômage et de l’inflation, forte accélération de la productivité) de l’économie américaine durant la décennie passée, plusieurs économistes ont évoqué l'émergence d'u... see more

En 2011, le marché postal sera entièrement libéralisé. Le service universel sera-t-il maintenu ? Comment sera-t-il financé ? Dans ce numéro de Regards économiques, nous abordons la question du financement du service universel postal dans un... see more

Pulsed excitation of small size monopole antennas for generating wideband electromagnetic pulses was used. The monopoles were excited by electrical pulses having rise times of 600 ps, 200 ps, 70 ps and voltages 100 V, 15 V, and 0.... see more

Ambiguity of depth estimation of magnetic sources via spectral analysis can be reduced representing its field via a set of space-frequency atoms. This is obtained throughout a continuous wavelet transform using a Morlet analyzing wavelet. In the phase-pla... see more

The construction of axially symmetric soliton solutions with non-zero Hopf topological charges according to a theory known as the extended Skyrme-Faddeev model, was performed in [1]. In this paper we show how masses of glueballs are predicted within this ... see more

In these lectures we consider Hitchin integrable systems and their relations with the self-duality equations and twisted super-symmetric Yang-Mills theory in four dimension. We define the Symplectic Hecke correspondence between different integrable system... see more
