Sobolev spaces and Poincaré inequalities on the Vicsek fractal

Fabrice Baudoin, Li Chen

In this paper we prove that several natural approaches to Sobolev spaces coincide on the Vicsek fractal. More precisely, we show that the metric approach of Korevaar-Schoen, the ap…

Dirichlet fractional Gaussian fields on the Sierpinski gasket and their discrete graph approximations

Fabrice Baudoin, Li Chen

We define and study the Dirichlet fractional Gaussian fields on the Sierpinski gasket and show that they are limits of fractional discrete Gaussian fields defined on the sequence o…

-Poincaré inequalities on nested fractals

Fabrice Baudoin, Li Chen

We prove on some nested fractals scale invariant -Poincaré inequalities on metric balls in the range . Our proof is based on the development of the local -…

A note on second order Riesz transforms in 3-dimensional Lie groups

Fabrice Baudoin, Li Chen

We prove explicit bounds for second order Riesz transforms of the sub-Laplacian in the Lie groups , and

Multiplier theorems via martingale transforms

Rodrigo Bañuelos, Fabrice Baudoin, Li Chen +1

We develop a new approach to prove multiplier theorems in various geometric settings. The main idea is to use martingale transforms and a Gundy-Varopoulos representation for multip…

BV functions and fractional Laplacians on Dirichlet spaces

Patricia Alonso Ruiz, Fabrice Baudoin, Li Chen +3

We study Besov critical exponents and isoperimetric and Sobolev inequalities associated with fractional Laplacians on metric measure spaces. The main tool is the theory of he…
