我们引入紧黎曼曲面的C-代数作为光滑函数的Poisson代数的非交换类似于。这些代数的表示产生了矩阵-代数序列,对于这些序列,矩阵交换子收敛到泊松括号为N→∞。对于球面和环面之间的一类特殊曲面,我们完全刻画了(甚至对于中间奇异曲面)相应C-代数的所有有限维表示。
We introduce C-Algebras of compact Riemann surfaces as non-commutative analogues of the Poisson algebra of smooth functions on . Representations of these algebras give rise to sequences of matrix-algebras for which matrix-commutators converge to Poisson-brackets as N → ∞. For a particular class of surfaces, interpolating between spheres and tori, we completely characterize (even for the intermediate singular surface) all finite dimensional representations of the corresponding C-algebras.
