On Bounding Harmonic Functions by Linear Interpolation


+ (y — y0) 2 = A can be written in the form 1 r « R(0 + v)u(R(d), 6) + R(9 + ir)u(R(d + T), 6 + ir) u(0) = — I dd, 2TTJ o R(6) + R(0 + T) where r = R(6) is the polar equation of the boundary. Thus the value of a harmonic function at any point in a circle is an average of the values obtained by linear interpolation of the boundary values at the ends of each… (More)
