I recently attended the Trimester Program: Prospect of Formal Mathematics in Bonn, the former capital of West Germany. 

For those interested, my presentation "Abduction Prover in Isabelle/HOL" is now available on YouTube: [Yutaka Nagashima: Abduction Prover in Isabelle/HOL](https://www.youtube.com/watch?v=9AlqFnc8QTY).

Additionally, I've made my presentation materials accessible for further reference: [2024_HIM_Yutaka.pdf](https://drive.google.com/file/d/12Rm13_UGlXTOCy2NRpWQd1GS5miCF28x/view?usp=sharing)

It was a rewarding experience to share and discuss advancements in formal mathematics with colleagues in this historic city.
