  1. Two positive solutions for second order three point boundary value problems with sign changing nonlinearities

    具有變號非線性項的二階三點邊值問題的兩個正解
  2. As an extension, we shall also consider similar problems for mixed quasimonotone reaction - diffusion systems with nonlocal boundary value conditions which kernel ki ( x, y ) is alternating sign. finally, in chapter 3, we use the above results to investigate the existence of positive periodic solutions and asymptotic behavior of solutions for the logistic equation with nonlocal boundary value conditions

    我們還將非局部邊值條件中的核函數k _ 1 （ x ， y ）推廣到不必定號的情況，對混擬單調反應擴散系統周期擬解的存在性及其局部漸近性態獲得了類似的上、下解方法。
