February 1, 2007

**The LIT Seminar ** was held on February 1, 2007 to mark the 60th anniversary of the Head of our Group, Professor Vladimir Gerdt. He presented talk "Computer algebra, integrability, involutivity and all that".

## About the Group

Group of Algebraic and Quantum Computations is a part of the Laboratory of Information Technologies (LIT)
of the Joint Institute for Nuclear Research (JINR). The main **research and activity directions** of the Group are:

1. Development of computer algebra methods, algorithms and software to solve scientific and technical problems arising
in research conducted at JINR and its member states.

2. Provision of the JINR users with information about non-commercial computer algebra systems and with open source software oriented
to symbolic and algebraic computation.

3. Information support of research in JINR based on the use of computer algebra; and of educational programs in
JINR relied on computer algebra software. Maintenance of the specialized Web server http://compalg.jinr.ru .

4. Elaboration and analysis of mathematical models for quantum computations and quantum informatics.

## Basic algorithms and software developed in the Group

**The most universal algorithmic method for investigating and solving systems of polynomial algebraic, differential and difference equations is the method of Groebner bases [1]. In the last 10 years new highly efficient involutive algorithms for computation of Groebner bases have been designed [2] and implemented in the GINV software [3].
An algorithmic extension of the involutive algorithm to systems of nonlinear partial differential equations has been done in [4]. An algorithmic approach to analyze discrete systems was developed in [5]. In paper [6] a Mathematica program was created to simulate quantum computation.
Symbolic-numeric algorithms for simulation of low dimensional nanostructures in external fields have been developed [7]. **
