Title: “Nonpositive immersions, local indicability and coherent groups”

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.
