作者: A Manning 摘要: The trouble with Newton's method for finding the roots of a complex polynomial is knowing where to start the iteration. In this paper we apply the theory of rational maps and some estimates based on distortion theorems for univalent functions to find lower bounds, ...
新版GRE数学复习重要考点：Finding Real Roots If (x-c) is a factor of the polynomial p(x), then c is a root of p(x).We can find the real roots of polynomial p(x) by finding all the factors of p(x).Example:p(x)=x2+3x+2=(x+1)(x+2). Two real roots of p(x...
For finding the real roots of a polynomial,we propose a clipping algorithmcalled SLEFEclipping and an isolation algorithmcalled SLEFEisolation algorithm.Ateach iterative step,the SLEFEclipping algorithm generates two broken lines bounding...
chebyshev basis, the red plots become only slightly worse than ratfun . indeed it is known that when looking for real roots of a polynomial, one is often advised to use chebyshev polynomials instead of monomials. the point here is that ratfun automatically finds an appropriate basis for the ...
In this Letter, we explore semi-definite relaxation (SDR) program for finding the real roots of a real polynomial. By utilizing the square of the polynomial, the problem is approximated using the convex optimization framework and a real root is estimated from the corresponding minimum point. When...
We can find the real roots of polynomial p by finding all the factors of p. Example: p=x2+3x+2=. Two real roots of p are -1 and -2. Remember: To find if c is a root of p, evaluate p and check if p=0. If x is a common factor of p, then zero is a root of p. 有...

This chapter highlights some of the struggles to solve fifth-degree polynomials as well as the development of the idea of a group and its application to answering the question of solvability of polynomial equations. It begins by surveying some of the methods by which mathematicians attempted to so...
