Boundedness of Positive Integral Operators on Lorentz-Gamma Spaces

R. Kerman, S. Spektor

We characterize the boundedness of a positive integral operator $T_K$, with kernel $K\in M_{+}({\mathbb{R}}^{2n})$, between Lorentz-Gamma spaces ${\Gamma }_{p,{\varphi }_2}({\mathbb{R}}^n)$ and ${\Gamma }_{q,{\varphi }_1}({\mathbb{R}}^n)$, $1<p\l…
