    本書主要討論邊界積分-微分方程的數學基礎理論,主要集中於把傳統的邊界積分方程中的超奇異積分轉化為帶弱奇性的邊界積分-微分方程。
    本書簡要地介紹了分佈理論,而邊界積分方程方法是基於線性偏微分方程基本解的,所以對微分方程的基本解也做了較為詳細的介紹。在餘下的章節里,本書依次討論了Laplace方程、Helmholtz方程、Navier方程組、Stokes方程等邊界積分-微分方程方法和理論。還討論了某系非線性方程如:如熱輻射、變分不等式和Steklov特徵值問題的邊界積分-微分方程理論。最後討論了有限元和邊界元的對稱耦合問題。
    本書可供計算數學與機械工程相關領域的研究人員和研究生參考使用。
