一维射线薛定谔算子等谱流形的连通性

Connectedness of the Isospectral Manifold for One-Dimensional Half-Line Schrödinger Operators

Fritz Gesztesy, Barry Simon

摘要:

设V_0是[0,\infty)上的实值函数,且\in L ^1([0,R])对所有R>0,使得H(V_0)= - \f{d^2}{dx^2} +V_0在L ^2([0,\infty))中具有离散谱,其中u(0)=0.设\calM(V_0)是V的集合,使得H(V)和H(V_0)具有相同的谱。证明了\calM(V_0)是连通的.

英文摘要:

Let V_0 be a real-valued function on [0,\infty) and V\in L^1([0,R]) for all R>0 so that H(V_0)= -\f{d^2}{dx^2}+V_0 in L^2([0,\infty)) with u(0)=0 boundary conditions has discrete spectrum bounded from below. Let \calM (V_0) be the set of V so that H(V) and H(V_0) have the same spectrum. We prove that \calM(V_0) is connected.
