摘要:

AbstractIn these lectures general relativity is outlined as the classical field theory of gravity, emphasizing physical phenomena rather than formalism. Dynamical solutions representing traveling waves as well as stationary fields like those of black holes are discussed. Their properties are investigated by studying the geodesic structure of the corresponding space‐times, as representing the motion of point‐like test particles. The interaction between gravitational, electro‐magnetic and scalar fields is also consi

摘要:

AbstractWe discuss our attempts to generalize the known examples of dualities inN= 1 supersymmetric gauge theories to exceptional gauge groups. We derive some dual pairs from known examples connected to exceptional groups and find an interesting phenomenon: sometimes the full global symmetry is “hidden” on the magnetic side. It is not realized as a symmetry on the fundamental fields in the Lagrangian. Rather, it emerges as a symmetry of the quantum theory. We then focus on an approach based on self‐dual models. We construct duals for some very special matter content ofE7,E6andF4. Again we find that the full global symmetry is not realized on the fundamental f
