On the zeros of \(J_n(z)\pm iJ_{n+1}(z)\) and \([J_{n+1}(z)]^2- J_n(z) J_{n+2}(z)\). (English) Zbl 0987.65022
The authors proves that the complex zeros of \(J_n(z)\pm iJ_{n+1}(z)\) and \([J_{n+1}(z)]^2-J_n(z)J_{n+2}(z)\) are simple. A software package for calculation zeros is used to illustrate the first 30 zeros.
