Abstract
Let m be a positive integer. We investigate the existence and the asymptotic behaviour of positive continuous solutions to the following coupled polyharmonic system in the unit ball B of ,
,
where ,
, r,
such that
and the functions a, b are nonnegative measurable on B satisfying some assumptions related to Karamata regular variation theory.
