本計畫的目的在硏究二階向量型微分束的反譜問題上，我們特別專注在半反問題上。 概言之，令P(x)和Q(x)皆爲定義在[0,]連續n x n矩陣，h和H皆爲n x n 實矩陣，我們想硏究下列向量型微分束可由幾組譜集和才能唯一決定P(x)和Q().
The purpose of this project is to study the half inverse spectral problem of the 2nd order differential pencil associated with the boundary condition wherei P(x) and Q(x) are two n x n matrix-valued continuous functions and h,H G That is, we want to know how many spectral set can determine P(x) and Q(x) uniquely if P(x) and Q(x) are priori known on.
