指数增长性的全纯函数的零点计数

Counting zeros of holomorphic functions of exponential growth

Johannes Sjoestrand

摘要:

研究了有界区域中依赖于小参数的全纯函数的零点个数,该函数在区域边界附近满足指数上界,在边界上的许多点处满足相似的下界.这样的零点的数目大致是$(2πh)^{-1}$乘以在主导指数的指数的拉普拉斯算子的域上的积分。M. Hager和Hager与作者的结果,它们在研究具有小随机扰动的椭圆算子特征值的渐近分布时是很重要的。在本文中,我们推广这些结果,并达到几何自然的陈述和自然的剩余估计。

英文摘要:

We consider the number of zeros of holomorphic functions in a bounded domain that depend on a small parameter and satisfy an exponential upper bound near the boundary of the domain and similar lower bounds at finitely many points along the boundary. Roughly the number of such zeros is $(2πh)^{-1}$ times the integral over the domain of the laplacian of the exponent of the dominating exponential. Such results have already been obtained by M. Hager and by Hager and the author and they are of importance when studying the asymptotic distribution of eigenvalues of elliptic operators with small random perturbations. In this paper we generalize these results and arrive at geometrically natural statements and natural remainder estimates.
