Integral Problems from a High-Dimensional Perspective: A Unified Analysis of Dimensional Elevation Methods and Techniques

经典的一维积分问题常因复杂性或隐蔽性难以揭示本质特征，本文通过将低维问题嵌入高维空间进行重构，借助多维积分理论(如积分换序、参数化技巧、积分号下求导等)进行求解，充分展现了高维理论对低维问题的统一化解题能力。这不仅为经典积分难题提供了全新的解决路径，还为跨学科问题的高维建模提供了重要的理论启示，拓展了高维方法在不同领域的应用前景。
Classical one-dimensional integral problems often struggle to reveal their essential characteristics due to inherent complexity or hidden structures. This study reconstructs these low-dimensional challenges by embedding them into higher-dimensional spaces, employing multidimensional integral theories (such as integration order interchange, parameterization techniques, and differentiation under the integral sign). This approach fully demonstrates the unified problem-solving capabilities of high-dimensional frameworks for low-dimensional issues. The methodology not only provides innovative solutions to classical integration conundrums, but also offers critical theoretical insights for high-dimensional modeling of interdisciplinary problems, significantly expanding the application potential of high-dimensional methods across diverse fields.
