Polynomials with only real zeros

K. Srimud, S. Tadee, V. Laohakosol

Abstract


Conditions which ensure that a combination of real polynomials, which have real interlacing zeros, continues to have only real zeros are derived. This gives a generalization of a result of Haglund and is proved using a unified method of Liu-Wang-Yeh.


Keywords


polynomials, real zeros, alternate, interlace
