| Abstract: | The authors study a semilinear cooperative system on the unbounded domain R~3.By establishing a new functional for the system and applying Z_2 version of the Mountain Pass Lemma,some sufficient conditions ensuring the esistence of infinitely many radially symmetric solutions are obtained.The results extend earlier publications. |
| Keywords: | semilinear cooperative elliptic system Z_2-Mountain Pass Lemma unbounded sequence |
