This is a concisely written survey for pure mathematicians, comprising many aspects of mathematical theories related to the so-called supersymmetric versions of Yang-Mills (YM) quantum gauge-field-theory models of strong interactions, as well as of the algebraic-geometry integrability of these and other models. The supersymmetry (SUSY) is a special form of an intrinsic invariance of a field model which includes bosonic and fermionic fields. The SUSY transformation mixes the bosonic and fermionic components. It is characterized by a number $$N$$ ($$1\leq N\leq 4$$) of independent generators. The central point in this survey is a review of a recent discovery of Seiberg and Witten, who put forward an exact solution to the $$N=2$$ SUSY version of the YM quantum field-theory model with the $$SU(2)$$ gauge group in four dimensions. Their exact solution is based on algebraic-geometry techniques (involving families of elliptic curves), the key point being to find the needed monodromy transformation.
The survey also reviews some other quantum-field models that can be solved exactly along similar lines. In particular, setting the mass constant of the model’s matter component equal to zero upgrades the SUSY order from $$N=2$$ to $$N=4$$.
