Conway topograph, PGL(2)(Z)-dynamics and two-valued groups
Conway’s topographic approach to the binary quadratic forms and Markov triples is reviewed from the point of view of the theory of two-valued groups. This naturally leads to a new class of commutative two-valued groups, which we call involutive. We show that the two-valued group of Conway’s lax vect...
