Hi, my name is Mike Winkler and I live at the North Sea in Cuxhaven-Sahlenburg, Germany.
My mathematical 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, nonperiodic tilings and Heesch’s problem. Other interests beside math: Nature & Horses, Classical Piano, E-Guitar, Cycling, Swimming, Painting.
