DESCRIPTION:I will discuss sequences of polynomials of a single variable t
 hat are orthogonal with respect to a vector of weights defined in the comp
 lex plane. Such polynomial sequences satisfy a recurrence relation of fini
 te (and fixed) order higher than 2. They share a number of properties that
  mimic those of standard orthogonality on $L_2$ spaces. The main focus wil
 l be on polynomial sequences possessing a three-star symmetry and whose mu
 ltiple orthogonality is preserved under the action of the derivative opera
 tor.
