We extend this result which is similar to ones of hirsch [ 1l ] and jiang [ 2 ] for 3 - dimensional cooperative system. furthermore, in the paper we discusse the cone of km, and obtain the similar result : theorem b : let f be a continuously differentiable cooperative vector field on d, suppose the following conditions hold : ( a ) d is pm - convex ; ( b ) every forward semi - orbit has compact closure in d ; ( c ) there is not more than one equilibrium p, then there is a unique equilibrium p and it is globally asymptotically stable
此外,本文還將在k _ m錐下討論此問題,並得到平行的結果:定理b :設f是d上一個連續可微的合作向量場,假設如下條件成立: ( a ) d是p _ m凸的; ( b ) d中的每一個正半軌道有緊閉包; ( c )至多有一個平衡點p ,則一定存在唯一的平衡點p ,並且是全局漸近穩定的。
