Query: On the convergence of Ces\`{a}ro means of negative order of double
  trigonometric Fourier series of functions of bounded partial generalized
  variation   The convergence of Ces\`{a}ro means of negative order of double trigonometric
Fourier series of functions of bounded partial $\Lambda$-variation is
investigated. The sufficient and neccessary conditions on the sequence $\Lambda
=\{\lambda_{n}\}$ are found for the convergence of Ces\`{a}ro means of Fourier
series of functions of bounded partial $\Lambda$-variation.
