Universal Algebra for Computer Science
by Eric G. Wagner
Publisher: Wagner Mathematics 2006
This is an online text on universal algebra with a strong emphasis on applications and examples from computer science. The text introduces some basic algebraic concepts, such as signatures, algebras, homomorphisms, initial algebras, free algebras, and illustrates them with numerous interactive applications to computer science topics.
