Yes it is true also for p = ∞. If you extend f to be zero outside U you have a Lipschitz function so you can use the fundamental theorem of calculus on segments parallel to the axes, say. f ( x) = f ( y 1, x 2, …, x n) + ∫ y 1 x 1 ∂ 1 f ( t, x 2, …, x n) d t = 0 + ∫ y 1 x 1 ∂ 1 f ( t, x 2, …, x n) d t,

WebApr 13, 2024 · For what it's worth, I'm looking at the book and Evans writes "This estimate is sometimes called Poincare's inequality." (Page 282 in the second edition.) See also the Wiki article or Wolfram Mathworld, which have somewhat divergent opinions on what should or shouldn't be called a Poincare inequality. Web8. Poincaré inequality is true if Ω is bounded in a direction or of finite measure in a direction. But not in general: if Ω = R, φ smooth with compact support and such that φ = 1 on [ 0, 1], φ ( x) = 0 if x ≥ 2 (bump function), φ n ( t) = φ ( t n), we have. ‖ φ n ‖ L 2 2 = ∫ 0 + ∞ φ ( t n) 2 d t = n ∫ 0 + ∞ φ ( s) 2 d s ...
