Web6. Any gradient vector eld F = hP(x;y);Q(x;y)imust satisfy P y = Q x from Clairaut’s theorem. This is called Clairaut’s test. Direct computation shows that F 2 does not satisfy the Clairaut’s test. For F 1, assume rf= F 1. Then f x = 2xy+ 2;f y = x2 + 1: From f x = 2xy+2, we know f(x;y) = x2y+2x+C(y) by taking antiderivative with respect ...

If $F$ is a field, what does the notation $F(x)$ mean?
Webof F[x] for F a eld. If 2F is a root of p(x), then it is a root of either a(x) or b(x). Proof. 0 = p( ) = a( )b( ). As Fis a eld, this forces either a( ) = 0 or b( ) = 0. 2 (A.2.10) Proposition.

Example of non-perfect field: F p ( T) = the field of rational functions in an unknown (transcendental element) T . Why? The polynomial f ( x) = x p − T ∈ F p ( T) [ x] is. ( 1) irreducible: Apply Eisenstein's Criterion in the UFD F p [ T] ⊂ F p ( T) and the prime T in it. and thus α is the unique root of f ( x), what makes ... routing history
