Nowak, Christine Some remarks on a paper by Samimi on nonuniqueness criteria for ordinary differential equations. (English) Zbl 0792.34002 Appl. Anal. 47, No. 1, 39-44 (1992). M. Samimi [Appl. Anal. 13, 291-296 (1982; Zbl 0464.34005)] gives nonuniqueness theorems for initial value problems \(x'=f(t,x)\), \(x(0)=x_ 0\), where \(f\) is not defined at \(t=0\). But the result for the scalar case only holds with the additional assumption that one solution exists. The applicability of the revised theorem is shown. The result for the \(n\)- dimensional case is generalized.
