Memories with Solomon Marcus

Abstract

I was interested in the work of Solomon Marcus in Mathematical Linguistics as a high-school student. Later, I had the opportunity to discuss with him about many topics. He was a polymath. We wrote a paper together, and I refereed an editorial paper about his work in 2021. Samples of (possible) discussions are presented: some topology conjectures, a self-dual theorem in geometry, results about Boolean algebras, a B-ring Euler formula, Yang-Baxter maps and a discussion on sequences and series. A short appendix on poetry is also included.
