Solving polynomial systems via triangular decomposition


Finding the solutions of a polynomial system is a fundamental problem with numerous applications
in both the academic and industrial world. In this thesis, we target on computing symbolically both
the real and the complex solutions of nonlinear polynomial systems with or without parameters. To
this end, we improve existing algorithms for computing triangular decompositions. Based on that,
we develop various new tools for solving polynomial systems and illustrate their effectiveness by
