Under iterated barycentric subdivision of a triangle, most triangles become flat in the sense that the largest angle tends to π. By analyzing a random walk on SL2(R) we give asymptotics with explicit constants for the number of flat triangles and the degree of flatness at a given stage of subdivision. In particular, we prove analytical bounds for the upper… CONTINUE READING
