摘　　要：本文分别针对变指数椭圆方程和系统建立了Pohozaev恒等式,并且在合适的条件下获得非平凡解的不存在性,从而推广了Dinca和Isaia(2010)和Lopez(2014)所获结果.In this paper, we obtain Pohozaev identities for the elliptic equation and system with variable exponent, respectively. Moreover, nonexistence of nontrivial solutions is derived under some suitable conditions, which extends the results of Dinca and Isaia(2010) and Lopez(2014).
