欧拉恒等式e^(ix)= cosx + isinx的矩阵推广

A matrix generalization of Euler identity e^(ix) = cosx + i sinx

Gianluca Argentini

摘要:

本文给出了复数指数表示的欧拉恒等式的矩阵推广。矩阵指数的概念是在一个基本的方式使用。本文定义了矩阵虚数单位的概念,它是通常的复数虚数单位的推广。这样得到的类欧拉恒等式与经典恒等式是相容的。此外,我们还导出了矩阵实部和虚数单位的指数表示,以及第一泡利矩阵的指数表示。

英文摘要:

In this work we present a matrix generalization of the Euler identity about exponential representation of a complex number. The concept of matrix exponential is used in a fundamental way. We define a notion of matrix imaginary unit which generalizes the usual complex imaginary unit. The Euler-like identity so obtained is compatible with the classical one. Also, we derive some exponential representation for matrix real and imaginary unit, and for the first Pauli matrix.
