Trace inequalities for fractional integrals in grand Lebesgue spaces
Trace inequalities for fractional integrals in grand Lebesgue spaces
rning the boundedness for fractional maximal and potential operators defined on quasi-metric measure spaces from $L^{p), \theta} (X, \mu)$ to $L^{q), q\theta/p}(X, \nu)$ (trace inequality), where $1< p< q< \infty$, $\theta> 0$ and $\mu$ satisfies the doub
