Simple roots of d_n

Given a root system we can always choose (in many ways) a set of positive roots. This is a subset of such that • For each root exactly one of the roots , is contained in . • For any two distinct such that is a root, . WebbContinuity of polynomial roots. It was recently brought up how to show that the n n roots of a real or complex polynomial depend continuously on the polynomial’s coefficients. Although I have used this proposition numerous times, implicitly and explicitly, I realized that I never saw a proof of it.

WebbDe nition 5. A base or simple system of a root system is a basis of such that every root can be written as an integer linear combination of elements of such that all coe cients are nonnegative or nonpositive. Roots in a base are called simple roots. De nition 6. A root is positive if and only if when written in terms of a base, its coe cients ...

WebbMultiple roots It can happen that a polynomial contains the same linear factor more than once. For instance, r 3-r 2-r+1=(r-1) 2 (r+1). Since the factor r-1 appears twice, we call 1 a double root of the polynomial, while -1 is a simple root. Note that also has a root at r=1.
