The main result of this paper is that common zeros in $${\mathbb{Z}}^ r$$ of a finite family of exponential-polynomial functions (with complex coefficients) lie ”near” affine subgroups explicitly given (they belong to such subgroups if only exponential functions are involved). Applications to algebraic equations relating values of linear recurrence sequences are given. Unfortunately the proofs, based on a theorem of Schlickewei are not effective.
