Abstract

Under some suitable assumptions, we show that the n+2 order non-linear boundary value problems (BVP"1){(E"1)[@f"p(u^(^n^)(t))]^''=f(t,u(t),u^(^1^)(t),...,u^(^n^+^1^)(t))(BC"1){u^(^i^)(0)=0,i=0,1,2,...,n-3,u^(^n^-^1^)(1)=0u^(^n^-^2^)(0)=@lu^(^n^-^1^)(@h)u^(^n^+^1^)(0)=@a"1u^(^n^+^1^)(@x)u^(^n^)(1)=@b"1u^(^n^)(@x) and (BVP"2){(E"2)[@f"p(u^(^n^)(t))]^''=f(t,u(t),u^(^1^)(t),...,u^(^n^+^1^)(t))(BC"2){u^(^i^)(0)=0,i=0,1,2,...,n-3,u^(^n^-^1^)(0)=0u^(^n^-^2^)(1)=-@lu^(^n^-^1^)(@h)u^(^n^+^1^)(0)=@a"1u^(^n^+^1^)(@x)u^(^n^)(1)=@b"1u^(^n^)(@x) have at least two positive solutions in C^n[0,1].
