We generalize a previous result concerning free martingale polynomials for
the stationary free Jacobi process of parameters λ∈]0.1],θ=1/2. Hopelessly, apart from the case λ=1, the polynomials we derive
are no longer orthogonal with respect to the spectral measure. As a matter of
fact, we use the multiplicative renormalization to write down the corresponding
orthogonality measure.Comment: page number : 1
