Initiated in 1985 by John Stephen Roy Chisholm (1926-2015) of the University of Kent at Canterbury, the International Conference on Clifford Algebras and Their Applications in Mathematical Physics (ICCA) reached in 2023 its 13th edition. This series of international conferences, previously organized in various countries, aims at bringing together the leading scientists and the young researchers in the field of Clifford algebras and their various applications in mathematics, physics, engineering and other applied sciences. The English mathematician and philosopher William Kingdon Clifford (1845-1879) is best remembered for his geometric algebras, nowadays better known in mathematics as Clifford algebras, named so in his honor, but he also contributed significantly to other branches of mathematics, especially geometry.
