Minimal-support variance conjecture for planar point-mass measures
Minimal-support variance conjecture for planar point-mass measures
Let be a finite point-mass probability measure on . Let be its finite support, let consist of support points having minimal mass, and let be the set of zeros of its Cauchy transform outside . Let denote the one-sided Hausdorff distance and let be the Chebyshev radius of .
Minimal-support variance conjecture.
The source notes that a related stronger claim fails for three-point measures and presents this restricted statement as one that still implies Sendov's conjecture. Its resolution is not given.
