The Hilbert Space of Double Fourier Coefficients for an Abstract Wiener Space
Fourier series is a well-established subject and widely applied in various fields. However, there is much less work on double Fourier coefficients in relation to spaces of general double sequences. We understand the space of double Fourier coefficients as an abstract space of sequences and examine r...
