... From the “Algebraic Structures” class you already know the basic constructions and properties concerning ideals and their quotient rings [G1, Chapter 8]. For our purposes however we have to study ideals in much more detail — so this will be our goal for this and the next chapter. Let us start with s ...

... on the line be in one-to-one correspondence with the real numbers. But how to achieve this when all one could define precisely are the rational numbers. Dedekind’s clever observation was that giving a rational number a is the same as giving the set τa of all the rational numbers to the left of, i.e., ...

... Jλ,n e1 = λe1 . Then for any linear operator B : V → V there exists a basis of V such that the matrix of B in this basis is a direct sum of Jordan blocks. This implies that all the indecomposable representations of A are Vλ,n = k n , λ ∈ k, with ρ(x) = Jλ,n . The fact that these representations are ...
