A unified treatment of the most important results in the study of fractional graph concepts, this volume explores the various ways in which integer-valued concepts can be modified to derive nonintegral values. It begins with the general fractional theory of hypergraphs and presents in-depth coverage of fundamental and advanced topics. Subjects include fractional matching, fractional coloring, fractional edge coloring, fractional arboricity via matroid methods, and fractional isomorphism. The final chapter examines additional topics such as fractional domination, fractional intersection numbers, and fractional aspects of partially ordered sets.Challenging exercises reinforce the contents of each chapter, and the authors provide substantial references and bibliographic materials. A comprehensive reference for researchers, this volume also constitutes an excellent graduate-level text for students of graph theory and linear programming.

Great work watch
Color: Black/Brown/White
What else is there to say, it’s a TIMEX.
The perfect JobSite watch, durable and accurate at a reasonable price.

It's a good look.
Color: Black/Brown/White, Color: Black/Brown/White
Very nice watch. I was complemented twice in 3 days. It fits well, looks great. I'm trying to look at screens less and teach my kids how to tell time on an analog clock face. 4 stars because, while the strap on the outside looks like it's a nylon/fabric wrist band, the inside is leather. My wrist has gotten pretty sweaty as a result. And there is a VERY audible 'tick' involved with this watch. I'm a contractor and have moderate hearing loss, but I've noticed the tick when I'm sitting quietly in my living room. If a ticking clock drives you nuts, I would not recommend. Most of the time, I am in a locale so noisy, it doesn't matter. They want a jeweler to change the battery, which, as a guy who fixes stuff, I don't love, but I've got some time before I think about that. No pun intended. I'm happy with this purchase. Good for the jobsite or a hot date with my wife.

Most Dependable and Accurate Watch I Have Ever Owned
Color: Black/Brown/White
I bought this watch in August 2022. It is now January 2026. I have worn it almost every day and every night. I mow my yard with it on, wear it for funerals and weddings but always take it off when taking a shower. I have owned many watches in my 77 years including a Rolex but will say this is the finest and most accurate watch I have ever owned. It is not fancy nor flashy but dependable and keeps PERFECT time. It is a timex and I am proud to wear it. My only recommendation is they enlarge the window showing the calendar day and wish they would include the day of the year. Thank you. A+
