Hypercomplex Analysis and Its Applications Extended Abstracts of the International Conference Celebrating Paula Cerejeiras’ 60th Birthday

This book contains a collection of short papers based on the presentations given at the international conference on Hypercomplex Analysis and its Applications celebrating Paula Cerejeiras’ 60th birthday. These papers present the latest results as well as overviews on specific topics in the areas of hypercomplex and harmonic analysis as well as their connections with partial differential equations and spectral theory.
