Some Modification on Interval Symmetric Single-Step Procedure for Simultaneous Inclusion of Real Zzeros of Polynomials

In this thesis, we discuss about the interval iterative procedures of bounding real zeros of polynomials simultaneously. We concentrate on the procedure that has been proposed by Monsi in 1988 that is the interval symmetric single-step procedure ISS1 and do some modifications on the procedure and co...
