The International Conference Past and Future Directions in Hypercomplex and Harmonic Analysis - Celebrating Frank Sommen’s 60th birthday to be held on March 29-April 2, 2016 will bring together experts in harmonic, complex and Clifford analysis. The objective is to celebrate Frank Sommen’s work, in particular, his fundamental contributions in higher-dimensional function theories, i.e. the theory of functions belonging to the kernel of the Laplacian, Cauchy-Riemann, or Dirac operators as well as higher spin operators. Applications of these function theories to mathematical physics, signal and image processing, operator theory and other areas of Applied Mathematics will also be topics of interest. Furthermore, talks in related areas like harmonic analysis, differential and integral geometry are also welcome. All these areas of Mathematics have been touched by Frank Sommen over the last 40 years and his works have been a source of inspiration for many mathematicians. The conference will be the perfect occasion to celebrate his 60th birthday among friends and collaborators.

The conference will host a poster session: we welcome young researchers (PhD students, PostDoc) working in an area within the topics of the conference to submit their abstract by January 10, 2016.

We are also pleased to announce the 21th European Intensive Course, to be held at the University of Aveiro, in the week after, on April 04-08, 2016.
