Comments on HW2:
Problem 6.6: K has a
unique extension of each degree. You should prove this by reducing the
statement to a first order one, and then noting that it holds for F_p.
To see the statement, think about what the elements of a field
extension generated by a given element look like. They are rational
functions of the generator (there is a unique generator by the
primitive element theorem). Now, using the degree bound, note that the
rational expressions look like quotients of bounded degree polynomials.
Quantify over the coefficients to show that the statement is first
order.
You can use part 6 to prove handle parts 3
through 5. It looks like part 4 can be solved with a little cleverness, using the
multiplicativity of the Legendre symbol, and looking for square roots.
Problem 6.8: Even if you don't care too much about the particular problem, I suggest looking at: Tao's blog.
