E Lp Norm const average le

DeGiorgi.eLpNorm_const_average_le

Plain-language statement

Jensen's inequality for eLpNorm: the L^p norm of a constant equal to the average is at most the L^p norm of the function. For 1 ≤ p < ⊤, an integrable f, and a finite measure μ: eLpNorm (fun _ => āØ x, f x āˆ‚Ī¼) p μ ≤ eLpNorm f p μ This is a consequence of Jensen's inequality for the convex function t ↦ |t|^p, proved here via Hƶlder's ine...
