Homomorphisms from the earring group to finite groups

Posted on June 7, 2014 by Jeremy Brazas

One of the the surprising things about the earring group (the fundamental group of the earring space ) is that the group of homomorphisms to the additive group of integers is countable (see this post for details) even though is … Continue reading →
