我们描述了一种由流形的cones - landi变形驱动的具有实数变形参数的2环面作用的谱三重体的变形方法。这种变形被证明具有与变形参数无关的自然同构k理论不变量。
We describe a way to deform a spectral triple with a 2-torus action parametrized by a real deformation parameter, motivated by the Connes–Landi deformation of manifolds. Such deformations are shown to have naturally isomorphic K-theoretic invariants independent of the deformation parameter.
