Examples
- By constructing approximate functions and using prior estimate and conversion of variable , it is proved that the inverse problem has weak solution for given initial value , boundary value and the oil output
通过变量和函数变换，作逼近函数和估计等方法，证明了对给定的初边值和石油产量，此反问题存在弱解。 - Using better prior estimate , the theory of brower degree and coincidence degree , the existence of positive periodic solution of a kind of neutral population model with multiple delays was studied , some sufficient conditions were obtained , which improve of the relational theorem
摘要通过更精确的先验估计，利用重合度理论中的连续定理，研究了一类时滞种群模型的周期解，获得了这类模型存在正周期解的充分条件，所得结果推广了有关结论，并使条件有所减弱。 - There are three sections in this paper . the first section : we consider the initial boundary value problem on half line and bounded interval , with kato ' s method for abstract quasi - linear evolution equations and a prior estimates of . solution , we get the existence of global smooth solution and the blow - up of solution in finite time under some conditions
第一部分：考虑了camassa ? holm方程在半无界和有界区域上的初边值问题，用kato关于拟线性演化方程的初值问题的理论及先验估计的方法，证明了整体解的存在性，及在一定条件下，解在有限时间内的blow ? up 。 - For the class of nonlinear second order ordinary differential equations ( odes ) , we firstly consider one of their special one - dimensional forms , and then prove the existence of solution to its two - point boundary value problem in the light of prior estimate and schauder fixed point theorem . we also show the exact solutions for the special equations as an example and plot the numerical solutions by mathematica
对于这类非线性的二阶常微分方程，我们首先考虑其一维的特殊的形式，运用先验估计，进而利用schauder不动点定理，证明了其两点边值问题解的存在性，并给出具体方程的解作为例子，然后用mathematica作出数值解的图。
