摘要：

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