I don't understand the sentence that begins the section labeled "Vanishing moments, polynomial approximation and smoothness". What is being defined by the math display? What is meant by the bar between (1+Z)^A and a(Z)? Divides? If this sentence needs fixing, I can try to fix it with some direction. --2601:404:CF80:1BC4:B40F:639F:3995:B411 (talk) 17:19, 3 August 2018 (UTC)
