Query: On Ces\'aro summability of Fourier series of functions from
  multidimensional Waterman classes   An analogue of D. Waterman's result on the summability of the Fourier series
for functions of bounded \Lambda-variation by the Ces\'aro methods of negative
order is obtained in multidimensional case. It is proved that, unlike
one-dimensional case, the continuity of function in the corresponding variation
is essential for the convergence and even for the localization of the Ces\'aro
means for certain orders of these means.
