Solving over-determined systems by the subresultant method
Thursday 21st March, 3-4pm
Carslaw Tutorial Room 360
In the talk I introduce the subresultant method to solve
over-determined multivariate polynomial systems over C.
The main idea is to construct a linear system such that
its solutions give either a rational representation of
the solution set of the polynomial system or an
approximation of it.
I will describe several constructions for such linear
systems, and sketch an argument why they are equivalent.
