Research Interests

In my thesis, we study some family of Thue equations. The method of solving these families consists of:

* searching the trivial solutions of these families;
* determining a fundamental system of units of the number field related with each equation;
* using the classical Siegel-Baker reduction of a Thue equation to a linear form of logarithms of algebraic numbers, using techniques from diophantine approximation, very accurate computations to prove that these families have no solutions except the trivial solutions, for a certain rank of the parameter.

My research, also focuses on other diophantine equations such as equations in relative fields, norm forms in two dominating variables, index form equations, Thue-Mahler equations, elliptic equations, hyperelliptic equations etc.
