Title: SymPy: Implementation of basic Parametrization module, Symmetry search and handle module.
Student: Yuri Karadzhov
Abstract: As for professional mathematician and physicist computer algebra system (CAS) mostly is the tool of handling simple yet technically large problems. Sure, it can solve some problems completely from the start to the end, but the main purpose we use CAS is to simplify our daily routine. So the goal of my project is improvement of base of Sympy which significantly reduce amount of repeated and cumbersome operations and give the basement for other more complex and specific tools. As for me this tools are – parametrization (which helps to solve ODE's and PDE's depending on arbitrary parameters) and concerned problem of searching and handling symmetries of single ODE or PDE or system of ones.

Currently in applied math department I study the theory of Lie groups and it's application to the differential equations. The most recent works however concerned with supersymmetry of Schrödinger-Pauli equation of arbitrary dimension. The obtained results widely extend the number of exactly solvable Quantum Mechanic problems as well as generalize the approach of finding such problems.
I've bin using GNU Linux since 2001. It is my only operation system for the last five years. I worked with Mandrake, Red Hat, Gentoo, Debian. Now I use Kubuntu as it is simple to configure and up to date. I used to work as system administrator so I familiar with sh.

The main purpose I applied to this project is to investigate in base of the sympy, which gives the ability to improve more complex functionality which I need in my research. I expect to continue my work on sympy after the end of the project, especially on differential and Lie modules, they are in great interest of me. Because after my work on SSQM will be finished I will recalculate and correct Amaldi classification which incomplete version is used in Maple to solve systems of ODE's and PDE's.
The project itself includes many steps, but the main goal is to implement parameter checking functionality (the idea is original and has no realizations in any other CAS).
e.g. Bernoulli differential equation <math> f'(x)=af^2(x)+b </math>
