Abstract

Professor Chern Shiing-Shen contributed to Geometry in many different ways, proving important results and, on many occasions, providing a view on how the field could move forward. One of his articles that both presented a remarkable synthesis of new developments and offered his vision for future ones is “The Geometry of $G$-structures,” published in 1966.

In the present text, I propose an analysis of the article’s main features. It also contains a testimony by Chern himself on how some of his main contributions came about and his view on what may come next, that proved remarkably correct.
