On the strong summability of the Fourier–Walsh series in the Besov space

UDC 517.5 The Fourier–Walsh series of even continuous functions may be divergent at some points.&nbsp;Moreover, among integrable functions, there are functions such that their Fourier–Walsh series diverge everywhere on $[0,1)$.&nbsp;&nbsp;In this connection, it becomes necess...
