Abstract We prove in this paper that a sequence M: Zⁿ → L(E) of bounded variation is a Fourier multiplier on the Besov space B^s_{p, q}(Tⁿ, E) for s ∈ R, 1 < p < ∞, 1 ≤ q ≤ 1 and E a Banach space, if and only if E is a UMD-space. This extends the Theorem 4.2 in [3] to the n-dimensional case. As illustration of the applicability of this results we study the solvability of two abstract Cauchy problems with periodic boundary conditions.

Palavras-chave : Fourier multipliers; operator-valued symbols; UMD-spaces; toroidal Besov spaces.
