Summary: Here, generalizing the class \((\Lambda^1,\Lambda^2)^{\ast} BV^{(p)}([0,2\pi]^2)\) to the class \((\Lambda^1,\Lambda^2)^{\ast} BV^{(p,q)}([0,2\pi]^2)\) of functions of \(p,q\)-\((\Lambda^1,\Lambda^2)^{\ast}\)-bounded variation, it is observed that the class is a Banach space with respect to the pointwise operations and the generalized variation norm. Moreover, we estimate the order of magnitude of multiple Fourier coefficients of a function of this class.
