Özet

The aim of this paper is to obtain the spectra and ne spectra of the matrix U(a; 0; b) on the Hahn space. Also, we explore some ideas of how to study the problem for a general form of the matrix, namely, the matrix U(a0; a1; : : : ; an􀀀1; 0; b0; b1; : : : ; bn􀀀1  ),where the non-zero diagonals are the entries of an oscillatory sequence.
