Hilbert's 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 ...
