Abstract

Abstract Let N ( T ; V ) N\left(T;\hspace{0.33em}V) denote the number of eigenvalues of the Schrödinger operator − y ″ + V y -{y}^{^{\prime\prime} }+Vy with absolute value less than T T . This article studies the Weyl asymptotics of perturbations of the Schrödinger operator − y ″ + 1 4 e 2 t y -{y}^{^{\prime\prime} }+\frac{1}{4}{e}^{2t}y on [ x 0 , ∞ ) \left[{x}_{0},\infty ) . In particular, we show that perturbations by functions ε ( t ) \varepsilon \left(t) that satisfy ∣ ε ( t ) ∣ ≲ e t | \varepsilon \left(t)| \hspace{0.33em}\lesssim \hspace{0.33em}{e}^{t} do not change the Weyl asymptotics very much. Special emphasis is placed on connections to the asymptotics of the zeros of the Riemann zeta function.

Morse势扰动的Weyl渐近性及其与Riemann-zeta函数的联系
抽象设N(T;V)N\left(T;\space{0.33em}V)表示Schrödinger算子−y〃+Vy-{y}^{^{\prime\prime}}+Vy的绝对值小于T的特征值的个数。本文研究Schrödinger算子−y〃+14e2t y-{y}^的扰动的Weyl渐近性^{2t}y在[x 0,∞)\left[{x}_{0},\infty)。特别地,我们证明了函数ε(t)\varepsilon\left(t)的扰动,其满足Şε(t。特别强调了与黎曼ζ函数的零的渐近性的联系。
