ON THE LOCATION OF ZEROS OF QUASI–ORTHOGONAL POLYNOMIALS WITH APPLICATIONS TO SOME REAL SELF–RECIPROCAL POLYNOMIALS

In this paper, we present new results on the location of zeros of some classes of quasi-orthogonal polynomials. From the Chebyshev polynomials, we obtain some classes of real self-reciprocal polynomials, and investigate the location and monotonicity of their zeros.
