The College of Education for Pure Sciences, Department of Mathematics, organized a lecture titled "A Simple Introduction to Some Word Functions." The lecture, presented by lecturer (Abu Faras Muhammad Jawad), covered symbolic dynamics and some definitions, starting with the topological transformation group. We learned about some of its types, such as the dispersed stream and the dynamic system. From the dispersed dynamic system, we can obtain the partial transition. We also learned about homomorphisms on topological transformation groups, then demonstrated how they can take their simplest forms and the nomenclature of their special cases on partial transitions. We then presented the word function, the endomorphism inherited from it, some of its types, and the resulting endomorphism
