摘要

In this paper, we obtain difference analogues of the second main theorem for meromorphic functions in several complex variables from which difference analogues of Picard-type theorems are also obtained. Our results are improvements or extensions of some recent results of papers [Proc. Royal Soc. Edinburgh Section A Math. 137, 457-474 (2007); Comput. Meth. Funct. Theor. 12, No. 1, 343-361 (2012)]. The method we used is very different from theirs.
