Fundaments of epimorphisms of profinite groups
Dan Haran
We propose and develop a theory that allows to characterize epimorphisms of profinite groups in terms of indecomposable epimorphisms.
Relatively projective pro- groups
Dan Haran, Pavel A. Zalesskii
It is known that the Kurosh Subgroup Theorem does not hold for pro- groups of big cardinality. However, a subgroup of a free pro- product is projective relative to the Ku…
-Hilbertianity and strong -Hilbertianity
Sela Fried, Dan Haran
-Hilbertianity and its strengthening, strong -Hilbertianity, are two generalizations of Hilbertianity inspired by Jarden's definition of -Hilbertianity and strong -Hilb…
Frobenius subgroups of free profinite products
Robert M. Guralnick, Dan Haran
We solve an open problem of Herfort and Ribes: Profinite Frobenius groups of certain type do occur as closed subgroups of free profinite products of two profinite groups. This also…
Permanence criteria for semi-free profinite groups
Lior Bary-Soroker, Dan Haran, David Harbater
We introduce the condition of a profinite group being semi-free, which is more general than being free and more restrictive than being quasi-free. In particular, every projective s…
