Abstract: We investigate q‐shift analogue of the lemma on logarithmic derivative of several variables. Let f be a meromorphic function in ℂn of zero order such that f(0) ≠ 0, ∞, and let q ∈ ℂn\{0}. Then we have m(r, f(qz)/f(z) ) = o(T(r, f)) on a set of logarithmic density 1. The q‐shift analogue of the first and the second main theorems of Nevanlinna theory of several variables and their applications is also shown.
