%0 Journal Article %T A duality principle for noncommutative cubes and spheres %A Teodor Banica %J Mathematics %D 2015 %I arXiv %X We discuss a general duality principle, between noncommutative analogues of the standard cube $\mathbb Z_2^N$, and nonocommutative analogues of the standard sphere $S^{N-1}_\mathbb R$. This duality is by construction of algebraic geometric nature, and conjecturally connects the corresponding quantum isometry groups, taken in an affine sense. %U http://arxiv.org/abs/1502.05315v3
