“…If p(r) = 4/(r3 (1 + r 4 ) 2 ), the k-Hessian equation(14) has no positive entire blow-up solutions. (ii) If p(r) = e r (4r −3 + r −2 ), the k-Hessian equation(14) has infinitely many positive entire blow-up radial solution.In fact, here k = 3, N = 7, f (x, u) = p(|x|)u 1/4 , andB(x) = x 2 . Thus we have L −1 (x) = x 1/3 and f (s, cu) = p(s)(cu) 1/4 p(s)c 1/3 u 1/2 = c 1/3 f (s, u)for all (s, u) ∈ (0, +∞) × [0, +∞), c ∈ (0, 1], which implies that (A) holds.…”
