real zeros. This result, which appears to be the first on this subject, shows that polynomials from .T’n do not behave like unrestricted polynomials. Schur 11 and by different methods Szeg6 12] and Erd6s and Turin [7] improve the above bound to c/n log n (see also [5]). In [6] we give the right upper bound of c/ff for the number of real zeros of polynomials from a large class, namely for all polynomials of the form
