The large-scale structure of the Universe and systems Clusters, and Groups of galaxies are topics like Superclusters, They fully justify the meeting on "e;Clusters of great interest.
The idea of holding a colloquium on Schmidt telescopes (techniques and science) originated from the observation that, in the last ten years and in spite of the remarkable developments and achievements in this field of astronomical research, there had been no specific opportunity for the experts to meet together, make the point on the state of the art, discuss and coordinate future plans.
The book aims to present current knowledge concerning the propagation of electro- magnetic waves in a homogeneous magnetoplasma for which temperature effects are unimportant.
