We examine the spectra and fine spectra of lacunary matrices over the sequence spaces
c0;c and `¥.
AMS Subject Classification: Primary 47A10; Secondary 47B37.
In 1975, Wenger [3] determined the fine spectra of Cesàro operator C1 on c, the space of convergent sequences. In [6], the spectrum of the Rhaly operators on c0 and c, under the assumption that {\disp...

In [6], Rhaly computed the spectrum of p-Cesaro operator on the Hilbert space l2 = {x = (xk): Sk IXkl2 < infinite}. In the present paper, we study the spectrum and fine spectrum for p-Cesáro operators...
