    abstract = "Using the operatorial approach, we investigate the ultrametric approximate solutions of the following Drygas functional equation: [Equation presented here] where K is an ultrametric valued field of characteristic zero, E is a K-vector space, F is a complete ultrametric space over K, f ∈ FE, Φ is a finite subgroup of the automorphism group of E with order /Φ/, and aλ ∈ E for all λ ∈ Φ. © 2016 by De Gruyter."
