Local-to-global fixed point properties for graphical C(4)-T(4) and C(6) small cancellation complexes
Karol Duda, Huaitao Gui
The paper proves that torsion subgroups of groups defined by certain graphical C(4)-T(4) and C(6) small cancellation presentations are finite, using local-to-global fixed point pro…

The small cancellation flat torus theorem
Karol Duda
We establish Flat Torus Theorem type results for groups acting on small cancellation complexes satisfying C(6), C(4)-T(4) and C(3)-T(6) conditions. For C(3)-T(6) complexes the resu…

Computable Folner sequences of amenable groups
Karol Duda, Aleksander Ivanov
The paper considers computable Folner sequences in computably enumerable amenable groups. We extend some basic results of M. Cavaleri on existence of such sequences to the case of…
