... to show that each Pi ⊆ K, which we do my induction. Since P0 = {0, 1}, it is clearly contained in K. Now suppose that Pi ⊆ K for some i. For z in Pi , its conjugate z̄ is also in Pi by (3), so (z + z̄)/2 and (z − z̄)/2i , the real and imaginary parts of z belong to K (observe that i belongs to K, it ...

Polynomial Resultants - University of Puget Sound
... The resultant of these two bivariate polynomials is a single univariate polynomial, so the variable x has been eliminated. This resulting polynomial shares properties with its parents, f (x, y) and g(x, y), but is easier to analyze than its parents. The example above illustrates an interesting prope ...

3 Factorisation into irreducibles
... • existence of a prime decomposition (i.e. there’s at least one way of splitting n as a product of primes); • uniqueness of prime decomposition - of course you can write the primes in a different order but, since the ring is commutative, that’s an inessential variation. You probably knew this fact ( ...
