## Abstract

In this article we prove the existence and uniqueness of a (weak) solution u in L_{p} ((0, T);Λ_{γ+m}) to the Cauchy problem (equetion presented) where d ∈ ℕ, p ∈ (1,∞], γ, m ∈ (0,∞), Λ_{γ+m} is the Lipschitz space on R^{d} whose order is γ + m, f ∈ L_{p} ((0, T),Λ_{γ}), and ψ (t, iΔ) is a time measurable pseudo-differential operator whose symbol is ψ(t, ξ), (equetion presented) with the assumptions (equetion presented) and (equetion presented): Furthermore, we show (equetion presented) where N is a positive constant depending only on d, p, γ, ν, m, and T, The unique solvability of equation (1) in L_{p}-Hölder space is also considered. More precisely, for any f ∈ L_{p}((0, T),C^{n+α}), there exists a unique solution u ∈ L_{p}((0, T),C^{γ+n+α}(R^{d})) to equation (1) and for this solution u, (equetion presented) where n ∈ ℤ_{+}, α ∈ (0, 1), and γ + α ∉ ℤ_{+}.
