Classroom: Zoom Meetings. Reference Books. During our regular course hours Friday , we will meet online using Zoom software. Before each online session I will send an email containing a link to all of you so that you can connect to the Zoom session.
Show all documents Applications of Semigroups The theory of automata has its origins in the work by Turing Shannon, and Heriken Turing developed the theoretical concept of what is now called Turing machines, in order to give computability a more concrete and precise meaning. Hannon investigated the analysis and synthesis of electrical contact circuits using switching algebra. The work of McCullon and pitts centers on neuron models to explain brain functions and neural networks by using finite automata. Their work was continued by Kleene. The development of technology in the areas of electromechanical and machines and particularly computers had a great influence on automata theory which traces back to the mids.

In theoretical computer science and formal language theory , a regular language also called a rational language   is a formal language that can be defined by a regular expression , in the strict sense in theoretical computer science as opposed to many modern regular expressions engines, which are augmented with features that allow recognition of non-regular languages. Alternatively, a regular language can be defined as a language recognized by a finite automaton. The equivalence of regular expressions and finite automata is known as Kleene's theorem  after American mathematician Stephen Cole Kleene. In the Chomsky hierarchy , regular languages are the languages generated by Type-3 grammars. See regular expression for syntax and semantics of regular expressions. Techniques to prove this fact rigorously are given below.
We end the chapter with an introduction to finite representation of languages via regular expressions. Strings. We formally define an alphabet.
Formal Languages and Automata Theory. A short summary of this paper. For example, we can show that it is not possible for a finite-state machine to determine whether the input consists of a prime number of symbols. Automata Theory is a branch of computer science that deals with designing abstract selfpropelled computing devices that follow a predetermined sequence of operations automatically. PDF download.
