Golod-Shafarevich infinitude criterion for pro-p groups
ID: golod-shafarevich-infinitude-criterion-for-pro-p-groups
If a pro- presentation on generators and possibly infinitely many relators satisfieswith the sum convergent and the Magnus degree of a free pro-p group element, then the presented pro-p group is infinite. The Golod-Shafarevich inequality forces its completed group algebra to be infinite-dimensional, which would be impossible for a finite group. This formulation applies to relators whose degrees tend to infinity and is suitable for enumerated power-relation constructions.
