Lejeune Dirichlet was a German mathematician. He studied mathematics in the Facult? des Sciences at the Coll?ge de France and later in 1825 he received an honorary doctorate from the University of Cologne. His first paper proved Fermat's Last Theorem for the case of n=5 and he went on to make valuable contributions in a number of fields of mathematics and mechanics. He is credited with proposing the modern definition of the function for sets of numbers. His work is significant to the UML because the operations defined in a UML classifiers are extensions of the theory of functions.
