设是连通有限图,且是通常的拉普拉斯图。利用变分法和上下解的方法,我们给出了Kazdan-Warner方程在V上有解的各种条件,其中是一个常数,是一个函数。我们还考虑了图上含有高阶导数的类似方程。我们的结果可以与Kazdan和Warner(Ann)的原始流形相比较。数学课。99(1):14-47,1974)。
Letbe a connected finite graph andbe the usual graph Laplacian. Using the calculus of variations and a method of upper and lower solutions, we give various conditions such that the Kazdan–Warner equationhas a solution onV, wherecis a constant, andis a function. We also consider similar equations involving higher order derivatives on graph. Our results can be compared with the original manifold case of Kazdan and Warner (Ann. Math. 99(1):14–47, 1974).
