Banaś, Józef; Rivero, Jesus Remarks concerning J. Witte’s theorem and its applications. (English) Zbl 0627.34073 Commentat. Math. Univ. Carol. 28, 23-31 (1987). The authors show uniqueness for the solution of the initial value problem \(\dot x(t)=f(t,x)\), \(x(0)=x_ 0\) using a generalization of a Kamke comparison function.
