小行星3789（3789 Zhongguo）(1928 UF) 是一个位于小行星带的小行星。 1928 UF于1928年10月25日由中国天文学家张钰哲在美国威斯康星州威廉斯湾（英语：Williams Bay）的葉凱士天文台发现，并命名为小行星1125（中华，China），后来失踪了。于1957年10月30日，1957 UN1在紫金山天文台发现，初时误以为是发现了先前丢失的1928 UF。小行星1125（中华）留给了1957 UN1，但1928 UF仍然没有找到。1986年，1986 QK1被发现，并证实为真正的1928 UF。此小行星被赋予新的名称和编号小行星3789（中国，Zhongguo），与先前的天体之中文名相同。

Il teorema, introdotto da Joseph Wedderburn per i soli anelli semplici, fu in seguito generalizzato da Emil Artin nella forma attuale. Indice 1 Enunciato 1.1 Corollari 1.2 Esempi 2 ...
