The case 1 < α < 2. %D 2017 %@ 1735-8787 %U http://hdl.handle.net/10498/35441 %X By using Blunck's operator-valued Fourier multiplier theorem, we completely characterize the existence and uniqueness of solutions in Lebesgue spaces of sequences for a discrete version of the Cauchy problem with fractional order $1 <\alpha< 2$. This characterization is given solely in spectral terms on the data of the problem, whenever the underlying Banach space belongs to the UMD-class. %K Maximal regularity %K Lebesgue spaces of sequences %K UMD Banach spaces %K R-boundedness %K lattice models %~ Universidad de Cádiz
