Abstract
The Riesz potential operator of variable order is shown to be bounded from the Lebesgue space with variable exponent into the weighted space , where with some and when is not necessarily constant at infinity. It is assumed that the exponent satisfies the logarithmic continuity condition both locally and at infinity and .
