Fractional stable random fields on the Sierpiński gasket
arxiv(2024)
摘要
We define and study fractional stable random fields on the Sierpiński
gasket. Such fields are formally defined as (-Δ)^-s W_K,α,
where Δ is the Laplace operator on the gasket and W_K,α is a
stable random measure. Both Neumann and Dirichlet boundary conditions for
Δ are considered. Sample paths regularity and scaling properties are
obtained. The techniques we develop are general and extend to the more general
setting of the Barlow fractional spaces.
