Title Promoter Affiliations Abstract "Algebraic structure and representations of concrete classes of algebras, groups and semigroups" "Eric Jespers" Mathematics "In this project we will treat fundamental structural issues of important algebraic constructions for which the interest still grows. The motivation comes from one side of classical algebraic constructions, like group rings, polynome rings and their generalizations, and from another side of the still growing interest and need for new algebraic methods in fast developing areas, such as quantum groups and their representations."
