考虑下面的二阶半线性特征值问题:这里D是RN中有界连通开区域,具有光滑边界,g:D→R的有界连续函数,在D中达到正、负值.f是上二阶连续可微的实函数,且满足k1X≥f(X)≥k2X,k1,k2>0,X>0.我们得到在λ充分大时,(*)有解;并且正数λ为(1)λ线性化方程的主特征值的充要条件是λ是(1)λ(2)的分歧点.(1)λ(2)有唯一分歧点(λ>0时). 相似文献

In this paper,we consider Schrodinger forms (operators) with singular magnetic vectorpotentials ─(▽—ia)2+Ⅴ. We prove that when the negative part V_ of electric potentialV satisfies(?) in dependentof V and a=(a1,a2,…,aN)∈Lloc2(RN)N, ─(▽—ia)2+Ⅴ has essential self-adjointextension F and it is the only self-adjoint realization of ─(▽—ia)2+Ⅴ. Moreover,We consider the continuity of (a,V) respect to a and V in the sense of strong resolvent. 相似文献
