This book gathers together selected contributions presented at the 3rd Moroccan Andalusian Meeting on Algebras and their Applications held in Chefchaouen Morocco April 12 14 2018 and which reflects the mathematical collaboration between south European and north African countries mainly France Spain Morocco Tunisia and Senegal. The book is divided in three parts and features contributions from the following fields: algebraic and analytic methods in associative and non associative structures; homological and categorical methods in algebra; and history of mathematics. Covering topics such as rings and algebras representation theory number theory operator algebras category theory group theory and information theory it opens up new avenues of study for graduate students and young researchers. The findings presented also appeal to anyone interested in the fields of algebra and mathematical analysis.
