Towards a Proof of the Riemann Hypothesis (RH)

November 19th, 2015

RiemannI shall report in a series of articles my investigation on the famous 150 years old conjecture made by Bernhard Riemann (1826-1866) in 1859. The purposes of the reports are threefold: First, this writing effort will force me to study thoroughly prior arts on this subject, which should help my research towards a possible proof of the Riemann hypothesis (RH). Second, when I submit new results to mathematical journals and/or post them on arXiv (an online publication website) , I can refer to these articles on my website as for the background information, which will allow my journal paper(s) to be more concise than would be, otherwise. Third, if I am successful in compiling prior arts and my own results in a cohesive manner, this series of articles will serve as core materials for a book or monograph.

Furthermore, I hope that this series will stimulate some readers and make them interested in this fascinating and profound subject. Tentative titles of the first few articles are as follows.

No. 1: Euler’s zeta function
No.2: Riemann’s zeta function and the Riemann hypothesis
No. 3: Riemann’s xi function and the product form representation
No. 4: The Fourier transform representation of the xi function

Lecture Slides of Probability, Random Processes and Statistical Analysis

December 20th, 2013

I am currently teaching a graduate course “ELE 525: Random Processes in Information Systems” at Princeton University on Mondays and Wednesdays in the Fall Semester 2013-14. I taught the same course in the Fall 2012-13. I post here the lecture slides, hoping that they will be useful to other instructors who will teach similar courses. The slides should be also useful to those who wish to study the subjects based on the textbook Probability, Random Processes and Statistical Analysis, by Hisashi Kobayashi, Brian L. Mark and William Turin (Cambridge University Press, 2012, 800 pages).
