... If x ∈ B, then the coefficients of charL/K (x) and min(x, K) are integral over A. In particular, TL/K (x) and NL/K (x) are integral over A, by (2.1.3). If A is integrally closed, then the coefficients belong to A. Proof. The coefficients of min(x, K) are sums of products of the roots xi , so by (2.1.4), i ...

6 Systems of Linear Equations
... This time we can consider a solution as a point in 3-dimensional space. The set of all solutions (assuming there are some) forms a plane in space. Exercise. What can the intersection of 2 planes in 3-space look like? Try to imagine all the possibilities, as we did for lines in the previous section. ...
