Abstract :
That several applications require the testing for zeros on the distinguished boundary of an unit polydisc of a multivariable polynomial has been noted. Here, procedures to. test whether or not a polynomial B(z_1 , z_2,\\cdots ,z_n) has zeros on |z_1| = |z_2| = \\cdots = |z_n|= 1 are developed. Two indirect tests are fornulated and the details of a direct test are given for the n = 2 case with possible extensions for the n > 2 case noted. Singular cases are given adequate attention.
