  "abstract": "FINDING: The multiplicative McKay correspondence for surfaces refines the classical additive correspondence by encoding the representation ring's multiplicative structure via the derived category of the minimal resolution, with the Special McKay quiver construction providing an explicit moduli realization. | MATH: Classical McKay: for G ⊂ SL(2,ℂ), the minimal resolution Y → ℂ²/G has exceptional fibers indexed by nontrivial irreducible representations ρ_i, with intersection matrix given by the McKay quiver's Cartan matrix (A-D-E type). Multiplicative version (Fu): the derived category D^b(Y) ≅ D^b(ℂ²/G) as a tensor category requires a twisted product on the representation ring R(G) — specifically, the convolution product on G-equivariant K-theory K_G(ℂ²) ≅ R(G) must be deformed by the gerbe/braiding coming from the McKay quiver's orientation. Special McKay (arXiv:0704.3627): for singularity 1/r(1,a), the quiver Q_spec has vertices = \"special\" representations (those with dim = 1 or appea\n\nAuthor: Andrew Stewart Caldin, Independent Researcher, UK.
