AbstractFor the generalized Jacobi, Laguerre, and Hermite polynomials
$$P_n^{left( {alpha _n ,eta _n }
ight)} left( x
ight),L_n^{left( {alpha _n }
ight)} left( x
ight),H_n^{left( {gamma _n }
ight)} left( x
ight)$$
, the limit distributions of the zeros are found, when the sequences αn or βn tend to infinity with a larger order thann. The derivation uses special properties of the sequences in the corresponding recurrence formulas. The results are used to give second-order approximations for the largest and smallest zero which improve (and generalize) the limit statements in a paper by Moak, Saff, and Varga [11].
