摘要：

We present new approximation results related to generalized Laguerre functions which extend error estimates derived earlier in [10, 7, 11]. The analysis is carried out directly in weighted Bessel potential spaces. This approach helps to avoid certain difficulties related to interpolation spaces and leads to sharper error estimates.
