| In 2022, Dr. Yitang Zhang proposed a new paper on the Landau-Siegel zeros conjecture. His paper gives the latest calculation method of the zero-point boundary of the L function and reduces the power to -2022. In this context, my graduation thesis integrates the advancement and achievements of many mathematics in history on the Riemann Hypothesis and Landau Siegel zeros conjecture, as well as my understanding of Professor Yitang Zhang’s new paper. This is a summary of historical results and focuses on the latest research results, which should be a comprehensive mathematical summary of the Landau-Siegel zero conjecture. |
