On entire solutions for an indefinite quasilinear system of mixed power
, 2014 We prove non-existence and existence of entire positive solutions for a Schrodinger quasilinear elliptic system. To prove the non-existence, we combine a carefully-chosen test function with some results that we proved concerning the positivity of a kind ...
