About me

Hi, there πŸ‘‹.

I'm Zixing Wang from China, a graduate student at the National University of Singapore with major in statistics. Broadly, I am interested in statistical analysis, modeling, prediction, and machine learning.

What i'm doing

  • think icon


    I always believe that real math is real fun.

  • book icon


    I like reading books, especially detective fictions.

  • cube icon

    Rubik's cube

    I play Rubik's cube and other puzzles.

  • Web development icon

    Web development

    I design and develop high-quality websites.

Research statement

My interest in statistics grew as my studies progressed, and I found that it was an intriguing area. It is possible to examine the data we collect utilizing the power of statistics. I am excited about statistics by a fascination with randomness, and it brings me to interact with researchers in many areas.

Future direction

I want to engage in statistical analysis, modeling and prediction, to learn and to discover with curiosity.

  1. Khovanov homology and knot concordance

    Dec. 2021 ‑ Jun. 2022

    This paper mainly studies the relations between Khovanov homology and knot concordance. Based on a variant of the Khovanov homology developed by Lee, we can construct the Rasmussen invariant. It provides a lower bound for the slice genus of a knot. For alternating knots, it equals the signature. As an application, we introduce Piccirillo's elegant proof, which shows that the Conway knot is not slice.

  2. A Generalized Determinant of Matrices and Applications

    Jun. 2019 ‑ Dec. 2020

    β€’ We gave a generalized definition of the determinant of matrices, which is compatible with the usual determinant for square matrices and keeps many important properties, such as being an alternating multilinear function, keeping multiplication formula and partly keeping the Cauchy‑Binet's formula. As applications of the new theory, the generalized Cramer's rule and the generalized oriented volume are obtained.

    β€’ This program was rated as outstanding program and supported by NSFC and NSF of Shanghai Municipal. Our team has already written a paper 'A Generalized Determinant of Matrices and Applications' and has submitted it to 'Algebra Colloquium'.


  1. BldDb

    Jun. 2022 ‑ Present

    BldDb is a 3x3x3 Rubik's cube blindfolded algorithms database. This website includes thousands of algorithms including 3-style corner (all buffers), 3-style edge (all buffers), corner twist, edge flip, etc. It supports simplified Chinese, English and Japanese, and is compatible with mobile phones, PCs and tablets. The website provides many options for each case, so the users can select algorithm based on their own preference.

  2. Commutator

    Mar. 2022 ‑ Present

    Let 𝐺 be any group. If π‘Ž, 𝑏 ∈ 𝐺, then the commutator of π‘Ž and 𝑏 is the element [π‘Ž, 𝑏] = π‘Žπ‘π‘Žβˆ’1π‘βˆ’1. This project is aimed at decomposing algorithms in commutator notation. For example, it decomposes π‘Žπ‘4π‘π‘π‘Žβˆ’1π‘βˆ’2π‘βˆ’1π‘βˆ’3 to [π‘Žπ‘, 𝑏3𝑐𝑏2 ].
