Abstract

We present a composite K-band luminosity function for 10 clusters at low redshift, where member galaxies are identified from an existing spectroscopic survey (the 2dF galaxy redshift survey). Our kinematically selected K-band luminosity function is well fitted by a Schechter function with MK=24.50+5loghM^*_K=-24.50 + 5\log h and α=0.98\alpha=-0.98 over 27<<MK5logh<22-27 < <M_K -5\log h < -22. This is very similar to the 2dF field value and suggests that the integrated mass accretion history of galaxies does not vary strongly with environment
