### Abstract

The two-dimensional classical Hardy spaces H_{p}(T×T) on the bidisc are introduced and it is shown that the maximal operator of the Cesàro means of a distribution is bounded from H_{p}(T×T) to L_{p}(T^{2}) (3/4

#_{1}(T×T), L_{1}(T^{2})) where the Hardy space H^{#}_{1}(T×T) is defined by the hybrid maximal function. As a consequence we obtain that the Cesàro means of a function f∈H^{#}_{1}(T×T) ⊃L log L(T^{2}) converge a.e. to the function in question.

As a consequence we obtain that the Cesàro means of a function f∈H#1(T×T) ⊃L log L(T2) converge a.e. to the function in question.
