Generalization of a Conjecture in the Geometry of Polynomials
In this paper we survey work on and around the following
conjecture, which was first stated about 45 years ago: If all the zeros of an
algebraic polynomial p (of degree n ≥ 2) lie in a disk with radius r, then,
for each zero z1 of p, the disk with center z1 and radius r contains at least
one zero of the derivative p′ . Until now, this conjecture has been proved for
n ≤ 8 only. We also put the conjecture in a more general framework involving
higher order derivatives and sets defined by the zeros of the polynomials
Adaptive Multiresolution Analysis on the Dyadic Topological Group
AbstractA type of multiresolution analysis on the space of continuous functions defined on the dyadic topological group is proposed, depending on free parameters. The appropriate choice of parameters is used to adapt this analysis to a given function
