Weak type (1,1) jump inequalities in a nonsymmetric Gaussian setting

Valentina Casarino, Paolo Ciatti, Peter Sjögren

We prove that the jump quasi-seminorm of order $\varrho =2$ for a general Ornstein--Uhlenbeck semigroup ${\left({\mathcal{H}}_t\right)}_{t>0}$ in ${\mathbb{R}}^n$ defines an operator of we…
