Unavoidable sets and harmonic measures living on small sets
Given a connected open set U 6= ∅ in Rd, d ≥ 2, a relatively closed set A in U is called unavoidable in U , if Brownian motion, starting in x ∈ U \A and killed when leaving U , hits A almost surely or, equivalently, if the harmonic measure for x with respect to U \ A has mass 1 on A. First a new criterion for unavoidable sets is proven which facilitates the construction of smaller and smaller u...
متن کاملFlat points in zero sets of harmonic polynomials and harmonic measure from two sides
We obtain quantitative estimates of local flatness of zero sets of harmonic polynomials. There are two alternatives: at every point either the zero set stays uniformly far away from a hyperplane in the Hausdorff distance at all scales or the zero set becomes locally flat on small scales with arbitrarily small constant. An application is given to a free boundary problem for harmonic measure from...
متن کاملStructure of Sets Which Are Well Approximated by Zero Sets of Harmonic Polynomials
The zero sets of harmonic polynomials play a crucial role in the study of the free boundary regularity problem for harmonic measure. In order to understand the fine structure of these free boundaries a detailed study of the singular points of these zero sets is required. In this paper we study how “degree k points” sit inside zero sets of harmonic polynomials in R of degree d (for all n ≥ 2 and...
متن کاملZero Sets of Solutions to Semilinear Elliptic Systems of First Order
Consider a nontrivial solution to a semilinear elliptic system of first order with smooth coefficients defined over an n-dimensional manifold. Assume the operator has the strong unique continuation property. We show that the zero set of the solution is contained in a countable union of smooth (n − 2)dimensional submanifolds. Hence it is countably (n − 2)-rectifiable and its Hausdorff dimension ...
متن کاملZero sets in pointfree topology and strongly $z$-ideals
In this paper a particular case of z-ideals, called strongly z-ideal, is defined by introducing zero sets in pointfree topology. We study strongly z-ideals, their relation with z-ideals and the role of spatiality in this relation. For strongly z-ideals, we analyze prime ideals using the concept of zero sets. Moreover, it is proven that the intersection of all zero sets of a prime ideal of C(L),...
