C. Fefferman [1, 2, 3] has shown that the multiple Fourier series of an
f
∈
L
p
,
p
>
2
f \in {L^p},p > 2
, may diverge a.e. when summed over expanding spheres, but converges a.e. when summed over expanding polyhedral surfaces. We show this dichotomy does not prevail for multiple Walsh-Fourier series.
