چکیده
|
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.
