如果对任意a \in R,有ua=au=a,则u是unity或叫multiplicative identity,记作1。 对trivial的ring {0}(我们叫zero ring)有0=1,所以我们只讨论non-trivial的情况。 === Ring Isomorphisms === 如果有一个bijective function能preserves algebra(包括加法和乘法),我们就说两个ring是isomorphic的。 === Domains ...
如果R是一个commutative ring w/ ideal I,我们记{I+r: r\in R}作R/I,念作R modulo I。其中的每一个元素叫做一个coset。 例子:Z/<4> = {<4>+n: n\in Z} = {<4>+0,<4>+1,<4>+2,<4>+3} 我们定义在R/I上的加法为(I+a)+(I+b)=I+(a+b),(I+a)(I+b)=I+ab。 Theorem. ...
