Francqcui chair mini-course
In the context of his Francqui chair, Professor Jaffard will give a mini-course entitled "Time-scale and time-frequency methods in the study of singularities of functions" at VUB from 16-19 April. This mini-course consists of four lectures and is intended for graduate students, Ph.D. students, and researchers interested in theoretical and applied harmonic analysis. More information on the mini-course can be found here. On 18-19 April the last two lectures of the mini-course will take place in the mornings and the workshop in the afternoon (see also the schedule below). It will be able to follow the last two lectures without having attended the first two.
The mini-course is free of charge. Please contact andreas.debrouwere@vub.be if you would like to participate.
Accomodation
A hotel very close to the VUB campus is the Aparthotel Adagio Access Brussels Delta. The university has an arrangement with this hotel. To use a reduced fee, a booking request has to be made by e-mail. Please mention that you will be participating in a workshop at VUB and that you would like use the VUB-corporate rates.
