In this article,we study the existence and non-existence of weak solutions to the fol-lowing quasilinear elliptic proble......

在各向同性高非线性光纤中同时考虑光纤损耗和抽运消耗对单抽运四波混频参变过程的影响，得到了导波光之间功率转化关系所满足的椭圆......

We sharpen and prove a conjecture suggested by Chen and Xie, which states that in Galerkineigenfunction discretization f......

讨论了二阶半线性椭圆方程△ｕ＋ｆ（ｕ）＝０在环域中的Ｄｉｒｉｃｈｌｅｔ问题，未对ｆ（ｕ）给出增长（临界）指数α＝ｎ＋２／ｎ－２的限制，给出了径向正解的先验估计，以及径向正解的存在唯一性。......
