We introduce the notion of Smarandache GT-algebras,
and the notion of Smarandache GT-Filters of the Smarandache

In this book we introduce the notion of interval semigroups
using intervals of the form [0, a], a is real. Several types of
interval semigroups like fuzzy interval semigroups, interval
symmetric semigroups, special symmetric interval semigroups,
interval matrix semigroups and interval polynomial semigroups
are defined and discussed. This book has eight chapters.
The main feature of this book is that we suggest 241
problems in the eighth chapter. In this book the authors have
defined 29 new concepts and illustrates them with 231
examples. Certainly this will find several applications.
The authors deeply acknowledge Dr. Kandasamy for the
proof reading and Meena and Kama for the formatting and
designing of the book.
