AI 中文摘要
我们在Lean 4中形式化了复值函数的拉普拉斯变换、其基本运算规则,以及通过实变量积分和狄利克雷积分证明的布罗米奇型逆变换定理。作为应用,我们形式化了谐振子的拉普拉斯域解,并将其变换与sin(ωt)的变换对应,还讨论了开发中遇到的主要分析和形式化挑战。
英文摘要
We present a Lean 4 formalization of the Laplace transform for complex-valued functions, its fundamental operational rules, and a Bromwich-type inversion theorem proved through real-variable integration and the Dirichlet integral. As an application, we formalize the Laplace-domain solution of the harmonic oscillator and identify its transform with that of $\sin(ωt)$. We also discuss the principal analytic and formalization challenges encountered in the development.
