Welcome to mikematics
On this website I present some of my work, thoughts and ideas on selected topics in mathematics. These range from conjectures over abstract ideas to rigorous proofs. My work is mostly in the areas of number theory, combinatorics and discrete geometry, including graph theory. If a problem has grabbed me, I worked on it over many years. My favorite topics are the 3x + 1 problem, regular matchstick graphs, non-periodic tilings and Heesch’s problem.
In the hope to enrich the mathematical world a little, enjoy reading and exploring this website.
