%C The manifold is developed from a fractional power eigenvalue matrix Bezier with determinant adjusted to one and a minimal value of b found by examination.

%t (* Fractional Pisot 3 X 3 Markov sequence *)

%t Clear[M, A, x]; digits = 21; b = -5/4; x = (n + 1)/n;

%t M = N[{{0.1, 0}, {1/2, (b + Sqrt[x])/6, 1/2, {1, b, -1}};

%t A[n_] := M.A[n - 1]; A[0] := {{0, 1, 1}, {1, 1, 2}, {1, 2, 2}};

%t (* flattened sequence of 3 X 3 matrices made with a Fractional Pisot recurrence *)
