Alexander Cruz Morales (MPI Bonn and UNAL Bogotá)
Alexander Grothendieck was one of the most influential figures
in mathematics during the last century and his legacy will remain for
the next centuries. During the 80's he wrote a series of mathematical
texts, some of them very well known, which have recently been made public by the
University of Montpellier. We want to discuss some of these texts,
and in particular one widely unknown manuscript entitled "Topology of the form",
in order to convey some understanding of what can be seen as his mathematical
testament (at least the first part of it).
