NOTES ON IDEALS 1. Introduction Let R be a commutative ring. An
... It is not obvious at first why the concept of an ideal is important. Here are two explanations why: (1) Ideals in R are precisely the kernels of ring homomorphisms out of R, just as normal subgroups of a group G are precisely the kernels of group homomorphisms out of G. We will see why in Section 3. ...

So it seems we have a connundrum on our hands. Example 2. A teacher announces to her class that there will be a surprise exam next ...

The earliest traces of numbers date back 150,000 years ago in Congo, when scratchings on a bone were found to be equally numbered on the front and back. In 4000 BC, Mesopota ...

7 Sequences of real numbers
... The most important application of sequences is the definition of convergence of an infinite series. From the elementary school you have been dealing with addition of numbers. As you know the addition gets harder as you add more and more numbers. For example it would take some time to add S100 = 1 + ...
