Toeplitz立方体的量子射影空间
Quantum projective space from Toeplitz cubes
摘要:
从Toeplitz代数的N-张量幂出发,构造了一个多重拉回C*-代数,它是复射影空间CP(N)的非交换变形.利用Birkhoff表示定理证明了多重拉回C*-代数的分支上的正则投影的核格是自由的。这表明我们的变形保持了由复射影空间的仿射覆盖生成的子集格的自由性。
英文摘要:
From N-tensor powers of the Toeplitz algebra, we construct a multipullback C*-algebra that is a noncommutative deformation of the complex projective space CP(N). Using Birkhoff's Representation Theorem, we prove that the lattice of kernels of the canonical projections on components of the multipullback C*-algebra is free. This shows that our deformation preserves the freeness of the lattice of subsets generated by the affine covering of the complex projective space.
