Summary: The spectral mapping theorem

$\sigma ( r ( a ) ) =r ( \sigma ( a ) )$ for Taylor and S\l odkowski spectra is proved when the operator family

$a$ generates a nilpotent Lie algebra and the family of noncommuting rational functions (and its limits)

$r$ generates an infinite-dimensional projective and weak quasinilpotent Banach Lie algebra.
