# Generalized Nets (World Scientific)

(Redirected from Generalized Nets, World Scientific)

**"Generalized Nets"** is a book by Krassimir Atanassov, published in 1991 by World Scientific Publishing house under ISBN 978-981-02-0598-0.

In the book, definitions and the basic properties of generalized nets are given. The GNs extensions and reductions are discussed.

GNs, which describe the functioning and results of the work of different types of Petri nets, different types of finite automata and of Turing machines, are given. Over the GNs are defined different operations, relations and operators.

Many open problems in the GNs theory are given.

This book is continued by the book "Applications of Generalized Nets", published in 1993.
