A brief history of G2. First Math Colloquium BCAM-UPV/EHU. BCAM-Basque Center for Applied Mathematics. November 17, 2016 - November 17, 2016
This colloquium will tell the tale of the exceptional simple Lie group G_2: from its unexpected discovery in 1887 to the present, where it has come to play an important role both in Differential Geometry and in Theoretical Physics (M-theory). This is a tale suitable for the whole family (of mathematicians); several reversals of fortune and periods of exile will befall our hero en route to present day influence.
