  New differential-recurrence properties of dual Bernstein polynomials are
given which follow from relations between dual Bernstein and orthogonal Hahn
and Jacobi polynomials. Using these results, a fourth-order differential
equation satisfied by dual Bernstein polynomials has been constructed. Also, a
fourth-order recurrence relation for these polynomials has been obtained; this
result may be useful in the efficient solution of some computational problems.
