... d). In the last problem set, we proved that addition/multiplication/division of algebraic numbers is algebraic (we used that when we reasoned why the ”algebraic-ness” of an extension is determined by its generators). So, the set of all algebraic numbers over F forms a field that contains F . Therefo ...

... between the roots of a polynomial and the roots of its derivative. For a polynomial P , we call the roots of its derivative critical points. First we need to state a result that is interesting in its own right and will be used in the proof of the Gauss-Lucas theorem. We will refer to a half-plane as ...

... This follows from the fact that f(x)-f(x)=0 for any polynomial and p(x)|0 for all polynomials, and we have that the relation is reflexive. (ii) Symmetry: f(x)~g(x) implies that g(x)~f(x) This follows from the definition of being divisible by p(x) p(x)|g(x)-f(x) ↔ g(x)-f(x)=q(x)p(x) for some polynomi ...

KadisonâSinger conjecture for strongly Rayleigh measures
... Oveis Gharan proved that the largest root of µ[v1 , . . . , vm ](x) is at most 4(2ε+ε2 ), where ε = ε1 +ε2 . We omit this part, as this is given in large detail in the next talk by Romanos Malikiosis. Then one applies Theorem 4 and obtains the existence of some S ∈ F such that all roots of qS are bo ...

... The polynomial mx (t) = td − a1 (x)td−1 + · · · + (−1)d ad (x) is called the minimum polynomial of x. Now suppose there are two minimum polynomials m1 (t) and m2 (t) for x. Then they both are monic (i.e. coefficient of the highest degree term is 1) and of the same degree, say d. But this means for m ...
