Özet

One of q-analogs of the Cesaro matrix of order one is the triangular matrix with nonzero entries c(nk) = q(n-k)/1+q+...+q(n), 0 <= k <= n, where q is an element of [0,1]. In this article, we will determine the spectrum of this matrix on the space of convergent sequences c. We will also obtain the fine spectral decomposition in the sense of Goldberg and a non-discrete spectral decomposition of the obtained spectrum.
