摘要

In this paper we are interested in examples of locally compact quantum groups (M,Δ)(M,\Delta) such that both von Neumann algebras, MM and the dual M^\hat{M}, are factors. There is a lot of known examples such that (M,M^)(M,\hat{M}) are respectively of type (I_,I_)(\rm{I}\_{\infty},\rm{I}\_{\infty}) but there is no examples with factors of other types. We construct new examples of type (I_,II_)(\rm{I}\_{\infty},\rm{II}\_{\infty}), (II_,II_)(\rm{II}\_{\infty},\rm{II}\_{\infty}) and (III_λ,III_λ)(\rm{III}\_{\lambda},\rm{III}\_{\lambda}) for each λ[0,1]\lambda\in [0,1]. Also we show that there is no such example with MM or M^\hat{M} a finite factor.
