General Reiteration Theorems for $\mathcal{R}$ and $\mathcal{L}$ Clases: Mixed Interpolation of $\mathcal{R}$ and $\mathcal{L}$-spaces

Pedro Fernández-Martínez, Teresa M. Signes

Given $E_0,E_1,F_0,F_1,E$ rearrangement invariant function spaces, $a_0$, $a_1$, $b_0$, $b_1$, $b$ slowly varying functions and $0<{\theta }_0<{\theta }_1<1$, we characterize the interpolatio…
