Abstract: DOI: 10.24193/subbmath.2022.4.12 Published Online: 2022-12-02 Published Print: 2022-12-30 pp. 829-840 VIEW PDF FULL PDF In this paper we have proved a theorem which show the degree of approximation of periodic functions by some generalized means of their Fourier series. In addition, our result is extended to two-dimensional setting as well. Mathematics Subject Classification (2010): 42A10, 42A16. Keywords: Fourier series, generalized de la Vallée Poussin means, degree of approximation, modulus of continuity, Fourier series. |
