Abstract
In the paper, by virtue of Wronski’s formula and Kaluza’s theorem for the power series and its reciprocal, and with the aid of the logarithmic convexity of a sequence constituted by central Delannoy numbers, the authors present negativity of several Toeplitz–Hessenberg determinants whose elements contain central Delannoy numbers and combinatorial numbers.
