Abstract.In this talk, we introduce quaternionic hyperbolicn-space and analogues of Jørgensen’s inequality for non-elementary groups of isometries of quaternionic hyperbolicn-space generated by two elements, one of which is loxodromic. As applications, we construct embedded collars about short, simple, closed geodesics in quaternionic hyperbolic manifolds.
