Tarski numbers and different solutions to configuration equations (1/4)
Apparaît dans la collection : Tarski numbers and different solutions to configuration equations
The main objective of this course is to give a constructive way to compute upper bounds for the Tarski number of groups. Indeed we use a finite system of equations, with no normalized solution and define configuration graphs, to obtain a paradoxical decomposition of the given group. We also give a new equivalent condition for locally finiteness of groups.
