We give a survey of the basic statistical ideas underlying the definition of entropy in information theory and their connections with the entropy in the theory of dynamical systems and in statistical mechanics.

Let $\Omega$ be a domain in $R^d$ and $d_\Gamma$ the Euclidean distance to the boundary $\Gamma$. We investigate whether the weighted Hardy inequality \[ \|d_\Gamma^{\delta/2-1}\varphi\|_2\leq a_\delta\,\|d_\Gamma^{\delta/2}\,(\nabla\varphi)\|_2 \] i

Let Ω be a domain in R d with boundary Γ, d Γ the Euclidean distance to the boundary and H = − div ( C ∇ ) an elliptic operator with C = ( c k l ) > 0 where c k l = c l k are real, bounded, Lipschitz functions. We assume that C ∼ c d Γ δ I

We establish that the Riesz transforms of all orders corresponding to the Grusin operator \(H_N=-\nabla _{x}^2-|x|^{2N}\,\nabla _{y}^2\), and the first-order operators \((\nabla _{x},x^\nu \,\nabla _{y})\) where \(x\in \mathbf{R}^n\), \(y\in \mathbf{

We establish existence of weighted Hardy and Rellich inequalities on the spaces $L_{p}(\unicode[STIX]{x1D6FA})$, where $\unicode[STIX]{x1D6FA}=\mathbf{R}^{d}\backslash K$ with $K$ a closed convex subset of $\mathbf{R}^{d}$. Let $\unicode[STIX]{x1D6E4
