  • A. A. Kon’kov

摘要

We show the exactness of the Kiguradze–Kvinikadze blow-up condition for solutions of the Cauchy problem \( w^{(m)} = f (t, w, \ldots , w^{(m - 1)}), \qquad w^{(i)} (0) = a_i \ge 0, \quad i = 0, \ldots , m - 1. \) w ( m ) = f ( t , w , , w ( m - 1 ) ) , w ( i ) ( 0 ) = a i 0 , i = 0 , , m - 1 .
