On approximation properties of semidirect products of groups
Goulnara Arzhantseva, Światosław R. Gal
Let R be a class of groups closed under taking semidirect products with finite kernel and fully residually R-groups. We prove that R contains all R-by-{finitely generated residuall…
Cancelation norm and the geometry of biinvariant word metrics
Michael Brandenbursky, Światosław R. Gal, Jarek Kędra +1
We study biinvariant word metrics on groups. We provide an efficient algorithm for computing the biinvariant word norm on a finitely generated free group and we construct an isomet…
Curvature spectra of simple Lie groups
Andrzej Derdzinski, Swiatoslaw R. Gal
The Killing form β of a real (or complex) semisimple Lie group G is a left-invariant pseudo-Riemannian (or, respectively, holomorphic) Einstein metric. Let Ω denote the multiple of…
