Fractional calculus for power functions (1103.3387v2)
Published 17 Mar 2011 in math.AP and math.PR
Abstract: We calculate the fractional Laplacian for functions of the form $u(x)=(1-|x|2)_+p$ and $v(x)=x_d u(x)$. As an application, we estimate the first eigenvalues of the fractional Laplacian in a ball.
