On Whitney-type extension theorems on Banach spaces for $C^{1, ω}$ , $C^{1, +}$ , $C_{loc}^{1, +}$ , and $C_{B}^{1, +}$ -smooth functions

Michal Johanis, Václav Kryštof, Luděk Zajíček

Our paper is a complement to a recent article by D. Azagra and C. Mudarra (2021). We show how older results on semiconvex functions with modulus $ω$ easily imply extension theorems…
