The true nature of quark confinement and chiral symmetry breaking in the real world of strong interactions, believed to be described by SU(3) Quantum Chromodynamics (QCD), still evades us.
Deep insights into the possible infrared dynamics of strongly-coupled nonAbelian gauge theories such as QCD come from the analyses of N=1 or N=2 supersymmetric gauge theories. I will review and discuss some of the beautiful ideas which were born in earlier studies of topological aspects of field theories, but since have been tested, clarified and enriched, especially in the context of supersymmetric world. Central in the whole discussion will be the topological soliton monopoles and vortices, their quantum dynamics, various dualities, anomalies, and the crucial role played by the flavor symmetries. Of particular interest will be confinement vacua near the strongly-coupled infrared fixed points.
I will briefly mention also some very recent results on the chiral symmetry breaking and confinement on chiral varieties of QCD.
