Reiteration formulae for the real interpolation method including L or R limiting spaces
We consider a real interpolation method defined by means of slowly varying functions. We present some reiteration formulae including so called $L$ or $R$ limiting interpolation spaces. These spaces arise naturally in reiteration formulae for the limiting cases $θ= 0$ or $θ= 1$. Applications to grand and small Lorentz spaces are given.
