六阶非线性边值问题的多变号解
Multiply Sign-changing Solutions for Sixth-order Nonlinear Boundary Value Problems
【摘要】 利用不动点定理和反对称延伸法研究六阶非线性边值问题变号解的存在性与多重性,当非线性项f满足一定条件时,我们得到该问题存在一个变号解.
【Abstract】 We study the existence and multiplicity of sign-changing solutions for six-order nonlinear boundary value problems by using fixed point index theory and anti-symmetrical extension method.When the nonlinearity f satisfies certain conditions,we obtain the result that this problem has a sign-changing solution.
