Each element of the set $\\{\\lambda_i^\\alpha\\}_{i=1}^\\infty$ of eigenvalues associated to $X^D_t$, regarded as a function of $\\alpha\\in(0,2)$, is right continuous. In addition, if $D$ is Lipschitz and bounded, then each $ \\lambda_i^\\alpha$ is continuous in $\\alpha$ and the set of associated eigenfunctions is precompact. We also prove that if $D$ is a domain of finite Lebesgue measure, then for all $0<\\alpha<\\beta\\leq 2$ and $i\\geq 1$, \\[\\lambda_i^\\alpha \\leq [ \\lambda^\\beta_i]^{\\alpha/\\beta}.\\] Previously, this bound had been known only for $\\beta=2$ and $\\alpha$ rational.", "revisions": [ { "version": "v1", "updated": "2004-07-19T01:49:17.000Z" } ], "analyses": { "subjects": [ "60J45", "26A33" ], "keywords": [ "stable processes", "finite lebesgue measure", "properties", "eigenvalues", "associated eigenfunctions" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2004math......7318D" } } }
