Determining explicit algebraic structures of semisimple group algebras is a fundamental problem, which has played a central role in the development of representation theory of finite groups. The tools of representation theory of finite groups extend in various ways to profinite groups such as compact linear groups over ring of integers of a local field (for example GL_n(Z_p)). However the continuous representations or even representation growth of profinite groups is not well understood and is one of the current exciting areas of research. The importance of computational methods in all pursuits of pure mathematics is no more obscure, and the subject has established itself as a powerful tool, aiding quick maturing of intuition about concrete mathematical structures. The focus of this program is on theoretical aspects of group algebras and representation theory of finite and profinite groups complemented by computational techniques using discrete algebra system GAP.The first part of this...
