We prove that if the Neumann eigenvalues of the impulsive Sturm–Liouville operator -D2+q{-D^{2}+q} in L2(0,π){L^{2}(0,\pi)} coincide with those of the Neumann Laplacian, then q=0{q=0}.

脉冲Sturm–Liouville算子的Ambarzumyan型定理
我们证明,如果L2(0,π){L ^ {2}(0,\ pi)}中的脉冲Sturm–Liouville算子-D2 + q {-D ^ {2} + q}的Neumann特征值重合与Neumann Laplacian的那些,则q = 0 {q = 0}。
