Abstract:
This paper continues the study of real zeros of Bessel functions begun in the previous parts of this work (see M. K. Kerimov, Comput. Math. Math. Phys. 54 (9), 1337–1388 (2014); 56 (7), 1175–1208 (2016)). Some new results regarding the monotonicity, convexity, concavity, and other properties of zeros are described. Additionally, the zeros of $q$-Bessel functions are investigated.
Key words:Bessel functions, $q$-Bessel functions, real zeros, monotonicity, convexity, and concavity of zeros, overview.
