Comments on "Necessary optimality conditions of an optimization problem governed by a double phase PDE"

Abstract

This note concerns the paper by Benslimane et Gadhi (JMAA. doi: 10.1016/j.jmaa.2023.127117) where the authors established necessary optimality conditions for an optimization problem (P) governed by a double phase partial di{\S}erential equation (Pf): Having noticed inconsistencies between the investigated problem (Pf ) and the weak formulation of the equation that is associated with it, we propose some modi\"O- cations that, from our perspective, correct the forthmentioned issue. Some careless mistakes and typos that caught our interest are also underlined and recti\"Oed.
