Abstract: In this paper, we study the well-posedness of the second order degenerate differential equation:(Mu')'(t)=Au(t) + Bu'(t) + Fut + f(t) (t ∈ T:=[0, 2π]) with periodic boundary conditions u(0)=u(2π),(Mu')(0)=(Mu')(2π), in Lebesgue-Bochner spaces Lp(T, X) and periodic Besov spaces Bp,qs(T, X). Using operator-valued Fourier multipliers theorems in vector-valued function spaces, we give necessary and sufficient conditions for the well-posedness of above equation.

Key words: Lebesgue-Bochner spaces, Besov spaces, Fourier multipliers, Well-posedness
