immersions, local indicability and coherent groups”

McGill University

Abstract:

A group G is locally indicable if every nontrivial finitely generated
subgroup of G has an infinite cyclic quotient.

A group G is coherent if every finitely generated subgroup of G is
finitely presentable.

I will discuss a certain Euler characteristic condition on a 2-complex
X which

implies that the fundamental group of X is both locally indicable and
coherent.
