摘要:

研究一维p-Laplace方程(p(u′(t)))′+q(t)f(t,u(t),u′(t))=0关于三点边值u(t)=u(1-t), u′(0)-u′(1)=u(1/2)对称正解的存在性. 利用AveryPeterson不动点定理得出该问题在一定的条件下至少存在3个对称正解及在f的适当假设下至少存在2n+1个对称正解.

关键词: p-Laplace方程, 对称正解, 三点边值问题, Avery-Peterson不动点定理

Abstract:

One dimension p-Laplace equation (p(u′(t)))′+q(t)f(t,u(t),u′(t))=0 with boundary value conditions u(t)=u(1-t), u′(0)-u′(1)=u(1/2) was studied. Under certain conditions the above problem has at least three symmetric positive solutions shown by virtue of the AveryPeterson fixedpoint theorem and at least 2n+1 symmetric positive solutions if the function f satisfies some additional conditions.

Key words: p-Laplace equation, symmetric positive solution, threepoint boundary value problem, AveryPeterson fixedpoint theorem
