Invariant Mean Value Property and Harmonic Functions
We give conditions on the functions σ and u on R such that if u is given by the convolution of σ and u, then u is harmonic on R.
متن کاملBODIES FOR WHICH HARMONIC FUNCTIONS SATISFY THE MEAN VALUE PROPERTY(x)
where „((?)= const depending on n. In this paper we consider the converse problem, namely: Suppose (0.1) holds for all harmonic functions, is S necessarily a sphere with center P (and consequently „^const)? The answer is in general negative, unless some assumptions are made on „. Thus, (0.1) is always satisfied with „(Q) = —dG(P, Q)/dv, G being Green's function of the Laplace equation in D and ...
متن کاملHarmonic functions via restricted mean-value theorems
Let f be a function on a bounded domain Ω ⊆ R and δ be a positive function on Ω such that B(x, δ(x)) ⊆ Ω. Let σ(f)(x) be the average of f over the ball B(x, δ(x)). The restricted mean-value theorems discuss the conditions on f, δ, and Ω under which σ(f) = f implies that f is harmonic. In this paper, we study the stability of harmonic functions with respect to the map σ. One expects that, in gen...
متن کاملA Mean Value Property of Harmonic Functions on the Interior of a Hyperbola
We establish a mean value property for harmonic functions on the interior of a hyperbola. This property connects their boundary values with the interior ones on the axis of the hyperbola from the focus to infinity.
متن کاملOn Polynomials Characterized by a Certain Mean Value Property
for xER, 0<t<ex (R denotes an «-dimensionaI region; x and yt are abbreviations for (xi, • • • , x„), (yn, • • • , ytn))We assume that the y<'s span £„ so that I^m^JV. We furthermore assume, without loss of generality, that yi, • • • , y« are linearly independent. Friedman and Littman [5] have recently shown that V consists of polynomials of degrees ^N(N—l)/2. This bound is actually attained whe...
