This volume provides comprehensive coverage of new developments in hypercomplex analysis and Clifford analysis. Contributions are based on talks given at the 9th European Congress of Mathematics minisymposium "e;Generalizations of Complex Analysis and Applications,"e; held in Spain in July 2024. Specific topics covered include:Hypercomplex integral transformationsSpinors, Lie algebras, Clifford (geometric) algebras and group theoryGeneralizations of the standard model of particle physicsFunction theoretical aspects and technological applications
