Title: Affine Reductions of Yang–Baxter Correspondences

Abstract:  In this talk, we discuss a geometric approach to constructing Yang–Baxter maps from affine Yang–Baxter correspondences. We explain how, under certain compatibility and transversality conditions, the intersection of two affine correspondences gives a unique map satisfying the Yang–Baxter equation. This provides a way to establish the Yang–Baxter property using affine geometry instead of checking the equation directly. We also discuss examples of this construction for KdV and Boussinesq systems, including their noncommutative generalizations.
