PARTIAL DIFFERENTIAL EQUATIONS: optimal design and numerics SUMMER SCHOOL-WORKSHOP
Benasque (Huesca-Spain) from 23 August to 4 September 2015



SCIENTIFIC ORGANIZERS:

Giuseppe BUTTAZZO, Università di Pisa, Italy
Olivier GLASS , Université Paris-Dauphine, France
Günter LEUGERING , Universität Erlangen, Germany
Enrique ZUAZUA , BCAM - Ikerbasque, Basque Country, Spain
 

The workshop is intended to provide a fruitful atmosphere for discussions and joint research work on themes involving partial differential equations and their applications to shape optimization, optimal control problems, singularities in fracture mechanics and fluid dynamics, and numerical analysis.

The work will be focused on new research trends in the fields above, in order to stimulate collaborations among participants by means of various activities on the basis of a daily programme (talks, seminars, minicourses, discussions...)

The activity is mainly intended for young scientists as PhD students and post-docs, and will be held thanks to the participation of a number of world leader mathematicians.
Limited partial financial support will be available for young researchers.
