内容简介
微分方程边值问题具有悠久的研究历史，是微分方程理论的一个重要分支。目前，国内外主要研究各类边值问题的解的存在性、多解存在性、正解存在性，为具体问题的求解提供理论基础，这提供了研究微分方程边值问题的必要性。研究微分方程边值问题的解的存在性理论的传统方法有：拓扑度理论、上下解方法。变分法越来越多地应用在解存在性研究中，逐渐成为研究非线性微分方程的主要工具，此方法能得到不同于其他传统方法的结果。《变分法及其应用：微分脉冲微分差分方程（英文版）》介绍变分法的主要结论和新进展，以及如何应用变分法到微分方程、脉冲微分方程、差分方程定解问题中，得到解的存在性、多解性、变号解和正解存在性。为了进一步研究解的性态，介绍了如何将变分法与上下解方法结合得到变号解存在性。这些研究丰富了解的存在性理论，扩展了变分法的应用范围。
