About Me
Hello! I'm Zichao Wang, and feel free to call me Franklin—after my favorite American historical figure, Benjamin Franklin. I am becoming a passionate research mathematician, currently in my third year of the Ph.D. program in Mathematics at Auburn University.
My academic journey began at Inner Mongolia University in Hohhot, where I studied Mathematics and physics. Recently, I earned my M.S. in Mathematics from Auburn University in 2024, graduating with a perfect GPA of 4.0.
I have a deep love for doing math, teaching math, and sharing math with others. My goal is to join the community of mathematicians and make meaningful contributions to the field. I am driven by the excitement of discovery, the challenge of solving problems, and the desire to leave a lasting impact through my research and dedication.
I also developed Texmail, a macOS application designed to help mathematicians communicate via email. With a simple keyboard shortcut, Texmail renders LaTeX code—including TikZ diagrams—into beautifully formatted formula images that can be pasted directly into any email client such as Gmail, Apple Mail, and Outlook. The software still has many imperfections, so please feel free to download it and contribute!
Research Interests
My research interests lie in homological algebra and derived categories, with a focus on singularity categories and differential graded (DG) algebra. I work under the guidance of Dr. Michael Brown.
Currently, I am working on computing the Serre functor for the singularity category of a Gorenstein differential graded algebra.
Paper
"We are continually faced with a series of great opportunities brilliantly disguised as insoluble problems." — John W. Gardner
- Wang, Z. (2024). Lower Bounds for Betti Numbers in Vietoris–Rips Complexes of Hypercubes. Master's Thesis, Auburn University. Advisor: Dr. Ziqin Feng.
In this thesis, I presented and analyzed the work of Henry Adams and Žiga Virk on new lower bounds for Betti numbers in Vietoris–Rips complexes of hypercube graphs across all dimensions and scales and corrected inaccuraies in their formula formulations.
Tutoring
"Every being cries out silently to be read differently." — Simone Weil
I have served as a teaching assistant for the following courses at Auburn University:
- College Algebra (MATH 1000)
- Calculus II (MATH 1620)
- Linear Differential Equations (MATH 2650)
- Topics in Linear Algebra (MATH 2660)
- Probability and Statistics II (STAT 3610)
Recommended Resources
"君子生非异也，善假于物也。" — 荀子
Here are some resources that I highly recommend:
- Computational Algebraic Topology by Dr. Vidit Nanda - Dr. Vidit Nanda is a Professor of Mathematics at the University of Oxford. His lecture notes and Zoom recordings on computational algebraic topology were immensely helpful when I was writing my master's thesis.
- Richard E. Borcherds' YouTube Channel - Richard E. Borcherds is a Fields Medalist, and his channel is a true master class. I often watch his lectures on number theory and commutative algebra.
- Immersive Translate - A tool that integrates OpenAI's ChatGPT API to assist in translating content, including newspapers and YouTube videos. It enables access to foreign news in languages such as Hebrew and Chinese, breaking through information barriers and broadening perspectives.
