Gröbner-Shirshov bases for extended modular, extended Hecke, and Picard groups
Eylem Güzel Karpuz, Ahmet Sinan Cevik · Mathematical Notes · 2012
In this paper, Gröbner-Shirshov bases (noncommutative) for extended modular, extended Hecke and Picard groups are considered. A new algorithm for obtaining normal forms of elements and hence solving the word problem in these groups is proposed.
