Discrete and global symmetries in particle physics -- CP violation -- CP violation: Experimental status and prospects -- Spontaneously broken symmetries -- Chiral symmetry -- Quark mass hierarchies, flavor mixing and maximal CP-violation -- Duality in quantum field theory (and string theory) -- Supersymmetry, strings and unification -- Abstracts of the seminars.

Symmetries and the breaking of symmetries play an important role in particle physics. Several experts in the field give overviews of different symmetry aspects in subatomic physics. Topics like CP violation, chiral symmetry, supersymmetry and spontaneous symmetry breaking are addressed. The articles are the written accounts of lectures given at the 1998 Schladming Winter School and address in particular graduate students. The material is dealt with in a comprehensive and detailed manner and is at the same time pedagogically well devised.
