Abstract
We obtain an integral formula for the distribution of the first hitting time of the origin for one-dimensional α-stable processes , where . We also find a spectral-type integral formula for the transition operators of killed upon hitting the origin. Both expressions involve exponentially growing oscillating functions, which play a role of generalised eigenfunctions for .
