Symmetrization of Bernoulli
Let X be a random variable. We shall call an independent random variable Y to be a symmetrizer forX , ifX+Y is symmetric around zero. If Y is independent copy of −X , it is obviously a symmetrizer. A random variable is said to be symmetry resistant if the variance of any symmetrizer Y , is never smaller than the variance of X itself. For example, let X be a Bernoulli(p) random variable. If p = ...
متن کاملSymmetrization, convexity and applications
Based on permutation enumeration of the symmetric group and ‘generalized’ barycentric coordinates on arbitrary convex polytope, we develop a technique to obtain symmetrization procedures for functions that provide a unified framework to derive new Hermite-Hadamard type inequalities. We also present applications of our results to the Wright-convex functions with special emphasis on their key rol...
متن کاملSkeleton-Intrinsic Symmetrization of Shapes
Enhancing the self-symmetry of a shape is of fundamental aesthetic virtue. In this paper, we are interested in recovering the aesthetics of intrinsic reflection symmetries, where an asymmetric shape is symmetrized while keeping its general pose and perceived dynamics. The key challenge to intrinsic symmetrization is that the input shape has only approximate reflection symmetries, possibly far f...
متن کاملSymmetrization of Vlasov-Poisson Equations
We detail the spectrum of the linearized Vlasov-Poisson equation, and construct an original integro-differential operator which is related to the eigenstructure. It gives a new representation formula for the electric field, and yields new estimates for the linear Landau damping. Then we apply the technique to a problem with a dependence to the Debye length, and show weaker damping for small Deb...
متن کاملSymmetrization of Convex Planar Curves
Given a closed convex planar curve, we call great chords the segment connecting two points with parallel tangents. We call great diagonals the support lines of the great chords and mid-parallels the lines through the mid-point of a great chord parallel to the corresponding tangents. Two curves are called parallel if the corresponding great diagonals are parallel. In this paper, we define the pa...
