Welcome to Sirawit’s Blog!
Here goes my thoughts and things, I guess…

Stacks
I actually wanted to write an introductory note on the basic Gromov–Witten invariant counting the number of rational curves passing through points in a general position, and how the recursive formula is obtained (the main reference is the classic Fulton–Pandharipande). But yes, again, I haven’t sufficiently understood the objects there, and my advisor also suggested…

Math 2.1 – A Rant
I’m extremely annoyed by the community response to this post, and my comments there seem to not be helping me (i.e. it seems like no one is convinced). So I’m here writing my own post (rant) in my own blog. First, I don’t like people who came into mathematics just because they want to solve…

Computer Vision and Algebraic Geometry
It might be weird for me to register for the computer vision course alongside my Master’s thesis, but as my friends know, I’m pretty much originally a gamer before I’m even started to be interested in mathematics (and then computer science). After playing some video games, I started to form another dream of building my…

I declare myself as an enemy to the mathematics community, and here’s why
I originally planned to write a blog post on algebraic geometry or computer vision today, but I haven’t sufficiently mastered what I wanted to write (yet), and more importantly, I’ve stumbled upon some opinions of the big mathematicians which I strongly disagree with. So let me state it clearly: I declare myself as an enemy…

The Bias-Variance Tradeoff, and the Cramér–Rao Lower Bound
First, the en dash in the title doesn’t mean that this article is AI generated. I’m still here. Today I attended a lecture in mathematical statistics, and it reminded me of some concepts from machine learning, so I want to synthesize a connection between them. Disclaimer: I’m neither an expert in statistics nor machine learning.…

On the Quasi-Riemann Hypothesis
Recent advances of AI have managed to solve the QRH, establishing that there are no nontrivial zeros of for . This was a huge deal. True, it still doesn’t settle the actual Riemann Hypothesis (yet), but this progress is enormous already. That’s why I want to take a look at it. Further progress is recorded…

Welcome to my new blog!
Hello everyone! After a while of going through bugs and then vibe coding, I’ve finally made the decision to migrate into WordPress. (It’s the easiest way tbh!) So this is my current new blog (this sentence is typed on 11.10.2026). I hope mathematics typesetting support is still there: we should have . The old one…
