简介：在这篇论文，我们在场为有限p组的等级的锋利的界限以它的coexponent。至于有p的有限p组奇怪，我们也给正常等级等于它的等级的一个足够的为条件。

简介：教无定法，教师在选择教学模式时，要视各方面的情况而定。笔者在普通中学工作多年，努力提高自身素质，经过不断地学习思考，不断的更新教育思想和理念，在生物教育教学实践中逐渐摸索出一种“三P”教学模式。这种“三P”教学模式适应面广，而且能灵活地融合其它的教学模式，符合人的认知规律，并且与新课改相适应。

简介：在这篇论文，作者学习单个p拉普拉斯算符方程−∆p在R−α+λg(x)uβ>N；在哪儿N≥3，1<p0，0<α<1，最大(p，2)<β+1<p*=。我们证明那在那里存在批评价值¤以便这个问题有至少二个答案如果0<λ<Λ；至少一个答案如果λ=Λ；并且没有答案如果λ>Λ。

简介：由在卡尔弗特和Gupta的非线性的accretivemappings的范围的和上使用不安理论，我们在答案u∈L~S的存在上学习抽象结果(包含p拉普拉斯算符操作员的非线性的边界价值问题的Ω)，在此2≤s≤+∞，并且(2N)/(N+1)<p≤2为N(≥1)它表示R~N的尺寸。获得结果，一些新技术在这篇论文被使用。在这里的这篇论文和我们的方法讨论的方程是扩展和补充到L.魏和Z.的相应结果他。
