Geometry and Topology of Singular Varieties. Theory and Applications

Version française


Report by Nguyen Viet Dung & Brasselet Jean-Paul

Report by Brigitte Lucquin & Christian Mauduit

Number of participants : 60 including 13 women

Objectives :

The main topics of the school cover Singularities in Geometry and Topology and their applications. More precisely it includes singularities of maps:singularities of polynomial maps, Jacobian conjecture, Milnor fibrations, and singularities of varieties : singularities of real and complex surfaces, characteristic classes, intersection homology, hyperplane arrangements.

Applications to medical imaging, astrophysics, computer vision or robotic will be
original features of the school.

The aim of the school is double : to provide an introduction to some current
problems for postgraduate students, young researchers and mathematicians in the region as well as to present recent advances and perspectives for more specialized researchers.

The aimed region is globally South Asia.

The school will be followed by a 4 days workshop.
