Abstract: Let denote the Cesàro sums of order of the Walsh functions. The estimates of given by Fine back in 1949 are extended to the case . As a corollary, the following properties are established for the rectangular partial sums of those double Walsh series whose coefficients satisfy conditions of bounded variation of order , and for some : (a) regular convergence; (b) uniform convergence; (c) -integrability and -metric convergence for ; and (d) Parseval's formula. Extensions to those with coefficients of generalized bounded variation are also derived.
