Seventh Spanish Symposium on Orthogonal Polynomials and Applications location:Granada, Spain date:23-27 September 1991
To study polynomials orthogonal with respect to the logarithmic equilibrium measure on the Julia set of a nonlinear polynomial P, Bessis and his coworkers introduced a symmetric bilinear form, the symmetric P-form. It is a non-Hermitian variant of a genuine inner product, the Hermitian P-form. The main reason for doing so was the existence of a three-term recurrence relation between the polynomials of successive degree of an orthogonal system.
