摘要：In this paper, we study the Pohozaev identity associated with a Henon-Lane-Emden system involving the fractional Laplacian:
   {(-Delta)(s)u = vertical bar x vertical bar(a)v(p), x is an element of Omega,
   (-Delta)(S)v = vertical bar x vertical bar(b)u(q), x is an element of Omega,
   u = v = 0, x is an element of R-n\Omega,
   in a star-shaped and bounded domain Omega for s is an element of(0, 1). As an application of our identity, we deduce the nonexistence of positive solutions in the critical and supercritical cases.
