Abstract

Interpolation inequalities for $C^{m}$ functions allow to bound derivatives of intermediate order $0 < j < m$ by bounds for the derivatives of order 0 and $m$ . We review various interpolation inequalities for $L^{p}$ -norms ( $1 \leq p \leq \infty$ ) in arbitrary finite dimensions. They allow us to study ultradifferentiable regularity by lacunary estimates in a comprehensive way, striving for minimal assumptions on the weights.
