 First-order reduction

First-order reduction, in general terms, refers to the process of simplifying a problem or a mathematical expression by reducing it to a first-order form, meaning that it involves only first-order terms. This concept appears in various fields, including physics, mathematics, and computer science, although its specific meaning can differ depending on the context. Below are a few interpretations: 1. **Mathematics**: In calculus, reducing a higher-order differential equation to a first-order equation can help in solving it.
