Wildan Bagus Wicaksono
Mathematics graduate, olympiad instructor, and author.
I hold a bachelor's degree in Mathematics from Universitas Brawijaya. My current research interests lie in number theory, with recent work on counting problems involving integer matrices. Alongside my research, I teach olympiad mathematics to students from elementary through senior high school and develop problems and learning resources.
Mathematics, writing, and education
A selection of the work that best represents what I am currently building and contributing to.
Statistics of centralizers of integer matrices
Recent work on counting integer matrices of bounded height that commute with a given matrix.

The Art of Olympiad Geometry
An Indonesian-language book that builds a foundation in olympiad geometry and introduces a broad range of problem-solving methods and perspectives. It is written for students who want to understand the reasoning behind a solution, not merely its final steps.

Number theory and counting
I am exploring counting problems in number theory, with recent work on integer matrices and their centralizers.
Olympiad teaching
I teach olympiad mathematics at elementary, junior high, and senior high school levels, helping students understand mathematical ideas and develop their problem-solving skills.
Problems and learning resources
I write olympiad problems and develop handouts, problem collections, and other learning resources for students and instructors.
A few milestones
My path in mathematics
My mathematical journey began with olympiad geometry and gradually grew into teaching, problem writing, and the book The Art of Olympiad Geometry.
Today, I am exploring research directions in number theory while continuing to teach and develop learning resources for olympiad students.
Let's talk mathematics.
I am always happy to discuss mathematics, olympiad education, teaching opportunities, or possible collaborations.
