Title: Homomorphism to R of semidirect products: a dynamical construction
Authors: Bettencourt, G. H.
Mendes, S.
Keywords: Random walks on groups
Homomorphisms
Semidirect product
Issue Date: 2015
Publisher: Natural Sciences Publishing
Abstract: We define a modified version of Erschler and Karlsson construction of homomorphisms from random walks [A. Erschler and A. Karlsson, Ann. Inst. Fourier (Grenoble) 60 (2010), no. 6, 2095−2113]. We show that our definition is well adapted to semidirect products. The same construction is conjectured to work also for other classes of maps like quasi-morphisms.
