DESCRIPTION:We will present a dilation technique from commuting endomorphi
 sms to commuting automophisms on a larger C*-algebra such that the corresp
 onding (minimal) Cuntz-Nica-Pimsner algebras are strong Morita equivalent.
  Hence we can reduce problems on semigroup actions to problems on group ac
 tions. Further consequences of our analysis include the association of the
  ideal structure/nuclearity/exactness of the Nica-Pimsner algebras with mi
 nimality-freeness/nuclearity/exactness of the C*-dynamics.   <br><br><br><
