摘要 利用五个泛函的不动点定理,证明了带有p-Laplacian算子的高阶微分方程组边值问题多组正解的存在性.其中n≥2,Φ_p(s)=|s|^(p^(-2))s,p>1. Using five functions fixed point theorem, we prove the existence of multiple positive solutions for boundary value problems of higher-order systems with p-Laplacian: {(Фp(u(n-1)(t)))'+p(t)f(t,u,v)=0,t∈(0,1)((Фp(v(n-1)(t)))'+q(t)g(t,u,v)=0,t∈(0,1)u(0)=0,u'(0)=…=u(n-2)(0)=0,Фp(u(n-1)(1))=m-2∑i=1aiФp(u(n-1)(ξi))v(0)=0,v'(0)=…=v(n-2)(0)=0,Фp(v(n-1)(1))=m-2∑i=1biФp(u(n-1)(ξi)) where n≥2,Фp(s)=|s|p-2s,P〉1.
