摘要:
In this study we construct self-similar diffusions on the Sierpinski carpet that are reversible with respect to the Hausdorff measure. The diffusions are obtained from self-similar diffusions reversible with respect to self-similar measures, which are singular to the Hausdorff measure. To do this we introduce a new sufficient condition for the continuity of sample paths to be preserved by a singular time change. (C) 2005 Elsevier B.V. All rights reserved.
