研究了一类椭圆型方程的稳定解,其中n ≥ 2,s ∈(0,1),λ ≥0,f是任意光滑正超线性函数.算子(-Δ)s代表分数拉普拉斯算子,一个2s阶的伪微分算子。根据λ的取值,研究了弱解u的存在性和正则性。
We investigate stable solutions of elliptic equations of the type where n ≥ 2, s ∈ (0, 1), λ ≥0 and f is any smooth positive superlinear function. The operator (− Δ) s stands for the fractional Laplacian, a pseudo-differential operator of order 2s. According to the value of λ, we study the existence and regularity of weak solutions u.
