%0 Journal Article %T Spectral mapping theorem for an evolution semigroup on a space of vector-valued almost-periodic functions %A Olivia Saierli %J Electronic Journal of Differential Equations %D 2012 %I Texas State University %X We give some characterizations for exponential stability of a periodic evolution family of bounded linear operators acting on a Banach space in terms of evolution semigroups acting on a special space of almost periodic functions. As a consequence, a spectral mapping theorem is stated. %K Periodic evolution families %K uniform exponential stability %K boundedness %K evolution semigroup %K almost periodic functions %U http://ejde.math.txstate.edu/Volumes/2012/175/abstr.html
