论文摘要
结果表明，统一的代数可以具有非零的点推导，而没有非平凡的格里森部分。相反，统一的代数可以具有非平凡的格里森部分，而没有非零，甚至可能无限的点派生。
It is shown that a uniform algebra can have a nonzero bounded point derivation while having no nontrivial Gleason parts. Conversely, a uniform algebra can have a nontrivial Gleason part while having no nonzero, even possibly unbounded, point derivations.
