Abstract    


  

Let  be a right-angled Artin group and Aut( ) be an automorphism group of . We have constructed a package RAAG (Finite Presentations of Automorphism Groups of right-angled Artin groups Algorithm) package, a GAP package for computation of a finite presentation for the automorphism group of a right-angled Artin group Aut( ). This package RAAG mainly installs new method to provide a finite presentation for Aut ( ).

 

Keywords: Right-angled Artin groups, RAAG, generators, relators, GAP system, automorphism, simple graph.
