My thesis: Difference equations arising from cluster algebras.
The data of solutions of Q-systems computed by the fermionic formulas: json file. See Theorem 13.11 in the paper written by Kuniba, Nakanishi, and Suzuki for a mathematical explanation. These data was used for computing the exponents in the paper Exponents associated with Y-systems and their relationship with q-series.
I'm interested in formalising mathematics. I formalized the definition of cluster algebras in Lean. I also made some contributions to mathlib (the Lean mathematical library). The main one is to write a library for bicategories, including the coherence theorem.
