In this paper, we study the following nonlinear Dirac equation (NDE)where , , is the mass of the electron, is an unknown parameter, is Planck’s constant, , , are 4 × 4 Pauli–Dirac matrices and . We present a new approach which is based on some prior estimates, and show that the spectrum point is a bifurcation point for equation (NDE) by using variational methods.

非线性狄拉克方程的分岔解
在本文中,我们研究了以下非线性狄拉克方程(NDE)在哪里,,是电子的质量,是未知参数,是普朗克常数,,,是 4 × 4 Pauli-Dirac 矩阵和. 我们提出了一种基于一些先前估计的新方法,并表明频谱点是使用变分法的方程 (NDE) 的分岔点。
