Extension operators for smooth functions on compact subsets of the reals
Leonhard Frerick, Enrique Jorda, Jochen Wengenroth
We introduce sufficient as well as necessary conditions for a compact set such that there is a continuous linear extension operator from the space of restrictions $C^\infty(K)=…

Stability of derivations under weak-2-local continuous perturbations
Enrique Jordá, Antonio M. Peralta
Let be a compact Hausdorff space and let be a C-algebra. We prove that if every weak-2-local derivation on is a linear derivation and every derivation on i…
