In this paper, Fourier analysis began as an attempt to approximate periodic functions with infinite summations of trigonometric polynomials. For certain functions, these sums, known as Fourier series, converge exactly to the original function. Hereextending the result of R. Islam & M. Zaman (1999), a theorem on βνμλ,,,k summability of quadruple Fourier series has been established.Refference:
