摘要: Abstract We show that Tr(−1) F e βH is an index for N = 2 supersymmetric theories in two dimensions, the sense it independent of almost all deformations theory. This related to geometry vacua (Berry's curvature) and satisfies exact differential equation as a function β. For integrable we can also compute thermodynamically, using S -matrix. The equivalence these results implies highly non-trivial set coupled integral equations with equations, among them Painleve III affine Toda equations.
