摘要
Let A(0) and A(1) be quasi-Banach spaces with A(0) hooked right arrow A(1). By means of a direct approach, we show that the interpolation spaces on (A(0), Al) generated by the function parameter t(theta) (1 + vertical bar log t vertical bar)(-b) can be expressed in terms of classical real interpolation spaces. Applications are given to Zygmund spaces L-p(log L)(b)(Omega), Lorentz-Zygmund function spaces and operator spaces defined by using approximation numbers.
