The matrix domain of the particular limitation methods Cesaro, Riesz, difference, summation and Euler were studied by several authors. In the present paper, certain topological properties and beta- and gamma-duals of the domain of a triangle matrix in a sequence space have been examined as an application of the characterization of the related matrix classes.
