Resum

Mass segregated stellar cusps are the natural configuration for nuclear 
stellar clusters in steady state with a central massive black hole of 
mass Mbh <~ few x 10^6 Msun. Detailed N-body and Fokker-Planck studies 
agree quite well with each other in the description of the bulk 
properties of the stellar distribution of such systems. For typical 
initial mass functions, the cluster is in the regime of strong mass 
segregation and therefore stellar-mass black holes dominate the spatial 
density in the innermost regions close to the massive black hole. As a 
natural consequence, the rates of extreme mass ratio inspirals 
detectable by LISA will be dominated by the inspiral of stellar-mass 
black holes.
