Continuous Linear Extension of Ultradifferentiable Functions of Beurling Type
Mathematische Nachrichten, 1993AbstractFor a weight function ω and a closed set A ⊂ ℝN let ℰ(ω)(A) denote the space of all ω‐Whitney jets of Beurling type on A. It is shown that for each closed set A ⊂ ℝN there exists an ω‐extension operator EA: ℰ(ω)(A) → ℰ(ω)(ℝN) if and only if ω is a (DN)‐function (see MEISE and TAYLOR [18], 3.3).

Almost Analytic Extensions and Ultradifferentiable functions
SINET: Ethiopian Journal of ScienceThe notion of almost analytic extension has found numerous applications in various fields. This paper provides a comprehensive characterization of ultradifferentiable functions by examining the existence of almost analytic extensions.
