We determine the degree of approximation of conjugate of a function belonging to Lip(ξ(t), p) class by matrix summability means of a conjugate series of a Fourier series. have determined the degree of approximation of a function belonging to Lip α by (C, 1), (C, δ), (N, p n), and (N, p n) means of its Fourier series. Working in the same direction Sahney and(More)
A good amount of work has been done on degree of approximation of functions belonging to Lipα, Lip(α, r), Lip(ξ(t), r) and W (L r , ξ(t)) classes using Cesàro and (generalized) Nörlund single summability methods by a number of researchers like Alexits [1], Sahney and Goel till now no work seems to have been done so far in the direction of present work.(More)
