Fractional and Hypersingular Operators in Variable Exponent Spaces on Metric Measure Spaces



We prove the continuity of potential type operators and hypersingular operators in variable Lebesgue and Sobolev spaces on a metric measure space (Χ, d, µ). Two variants of such operators are considered, according to the regularity admitted on the measure µ.
