摘要
We establish the sharpness of recently-obtained embedding theorems for certain logarithmic Bessel potential spaces modelled upon generalized Lorentz-Zygmund (GLZ) spaces. The target spaces may be of GLZ or Holder type, including in particular spaces of 'almost Lipschitz' type familiar from the work of Brezis and Wainger.
