Grupos y geometría cubular

This survey paper, written in spanish, is an extended version of lecture notes for a mini-course taught at the 2022 Summer School in Geometric Group Theory, which took place in the Centro de Ciencias Matemáticas in Morelia, Mexico in July 2022. Its main aim is to give an introduction to the study of non-positively curved cube complexes, and through these, to introduce the reader to geometric group theory.
