Integrability of Superharmonic Functions and Subharmonic Functions
نویسنده
چکیده
We apply the coarea formula to obtain integrability of superharmonic functions and nonintegrability of subharmonic functions. The results involve the Green function. For a certain domain, say Lipschitz domain, we estimate the Green function and restate the results in terms of the distance from the boundary.

On the mean value property of superharmonic and subharmonic functions
Recall that a function u is harmonic (superharmonic, subharmonic) in an open set U ⊂ Rn (n ≥ 1) if u ∈ C2(U) and Δu = 0 (Δu ≤ 0,Δu ≥ 0) on U . Denote by H(U) the space of harmonic functions in U and SH(U) (sH(U)) the subset of C2(U) consisting of superharmonic (subharmonic) functions in U . If A ⊂ Rn is Lebesgue measurable, L1(A) denotes the space of Lebesgue integrable functions on A and |A| d...
متن کاملSubharmonic Functions, Mean Value Inequality, Boundary Behavior, Nonintegrability and Exceptional Sets
We begin by shortly recalling a generalized mean value inequality for subharmonic functions, and two applications of it: first a weighted boundary behavior result (with some new references and remarks), and then a borderline case result to Suzuki’s nonintegrability results for superharmonic and subharmonic funtions. The main part of the talk consists, however, of partial improvements to Blanche...
متن کاملA Generalized Mean Value Inequality for Subharmonic Functions and Applications
If u ≥ 0 is subharmonic on a domain Ω in Rn and p > 0, then it is well-known that there is a constant C(n, p) ≥ 1 such that u(x)p ≤C(n, p)M V (up,B(x,r)) for each ball B(x,r) ⊂ Ω. We recently showed that a similar result holds more generally for functions of the form ψ◦ u where ψ : R+ → R+ may be any surjective, concave function whose inverse ψ−1 satisfies the ∆2-condition. Now we point out tha...
متن کاملUniqueness of ∞-harmonic Functions and the Eikonal Equation
Comparison results are obtained between infinity subharmonic and infinity superharmonic functions defined on unbounded domains. The primary new tool employed is an approximation of infinity subharmonic functions that allows one to assume that gradients are bounded away from zero. This approximation also demystifies the proof in the case of a bounded domain. A second, quite different, topic is a...
متن کاملOptimal Stopping Games and Nash Equilibrium
We show that the value function of the optimal stopping game for a rightcontinuous strong Markov process can be identified via equality between the smallest superharmonic and the largest subharmonic function lying between the gain and the loss function (semiharmonic characterisation) if and only if the Nash equilibrium holds (i.e. there exists a saddle point of optimal stopping times). When spe...
