On $L^{p}$ -contractivity of Laguerre semigroups

Adam Nowak, Krzysztof Stempak

We study several Laguerre semigroups appearing in the literature and find sharp ranges of type parameters for which these semigroups are contractive on all $L^{p}$ spaces, $1\le p \l…

A symmetrized conjugacy scheme for orthogonal expansions

Adam Nowak, Krzysztof Stempak

We establish a symmetrization procedure in a context of general orthogonal expansions associated with a second order differential operator $L$ , a `Laplacian'. Combined with a unifi…

Negative powers of Laguerre operators

Adam Nowak, Krzysztof Stempak

We study negative powers of Laguerre differential operators in $R$ , $d \geq 1$ . For these operators we prove two-weight $L^{p} - L^{q}$ estimates, with ranges of $q$ depending on $p$ . The…
