Dynamical Systems Seminar 主講者: 洪國智 教授 (勤益科技大學基礎通識教育中心) 講題: Global bifurcation of bifurcation curves of a multiparameter problem 時間: 2014-05-07 (Wed.)  15:00 - 16:30 地點: 數學所 722 研討室 (台大院區) Abstract: We study the exact multiplicity of positive solutions of the semilinear problem $\left\{ \begin{array}{l} u^{\prime \prime }(x)+\lambda f_{\varepsilon }(u)=0\text{,}\;\;-10$ is a bifurcation parameter, $\varepsilon >0$ is an evolution parameter and the nonlinearity $f\in C^{2}[0,\infty )$. More precisely, we investigate the global bifurcation of bifurcation curves for varying $\varepsilon >0$. || Close window ||
