The Classical Maximum Principleial operators of the form.where . = (.., … , ..) lies in a domain Ω of ℝ., . ⩾ 2. It will be assumed, unless otherwise stated, that . belongs to ..(Ω). The summation convention that repeated indices indicate summation from 1 to . is followed here as it will be throughout. . will always denote the operator (3.1).
