Factorization Of Polynomials And Real Analytic Function, Radoslaw L. Stefanski
Honors Theses
In this project, we address the question: When can a polynomial p(x, y) of two variables be factored as p(x, y) = f(x)g(y), where f and g are polynomials of one variable. We answer this question, using linear algebra, and create a Mathematica program which carries out this factorization. For example,
3+3x-5x^3+y+xy-5/3x^3y+y^2+xy^2-5/3x^3y^2 = (1+x-5/3x^3)(3+y+y^2)
We then generalize this concept and ask: When can p(x,y) can be written as
p(x,y) = f1(x)g2(y)+f2(x)g2(y)+...+fr(x)gr(y)
where fj,gj are polynomials. This can certainly be done (for large enough r). Which is the minimum such r? Again, we have a Mathematica program which carries out this …
