One of the most widely used texts in its field, this volume introduces the differential geometry of curves and surfaces in both local and global aspects. The presentation departs from the traditional approach with its more extensive use of elementary linear algebra and its emphasis on basic geometrical facts rather than machinery or random details. Many examples and exercises enhance the clear, well-written exposition, along with hints and answers to some of the problems.The treatment begins with a chapter on curves, followed by explorations of regular surfaces, the geometry of the Gauss map, the intrinsic geometry of surfaces, and global differential geometry. Suitable for advanced undergraduates and graduate students of mathematics, this text's prerequisites include an undergraduate course in linear algebra and some familiarity with the calculus of several variables. For this second edition, the author has corrected, revised, and updated the entire volume.

Great enrichment activity for dogs!
Color: Blue Green Orange, Color: Blue Green Orange
This mat provides excellent enrichment time for scent hounds. Our mini dachshund puppy loves finding treats hidden in the mat. It is also a very affordable option. Our puppy likes to play and sleep on it even when there aren’t treats in it. If your dog is an aggressive or obsessive chewer, I would only leave out when treats or food are hidden inside and then pick up because it will get damaged.

Great puzzle mat!
Color: Blue Green Orange, Color: Blue Green Orange
My boys love these snuffle mats. Since I bought them, they are always excited when I pull them from the cabinet. It keeps them busy for a while, and they don't eat their kibbles too quickly. It's simple to clean; I just put it in the washer and hang it to dry. Suitable for small dogs, such as my babies.

DON’T WASTE YOUR MONEY-it is CRAP!!!
Color: Blue Green Orange
What a Piece of Garbage! If I could I’d have given this ZERO STARS!!! My Dogs WON’T GET NEAR IT! Obviously it smells wrong or they sense that it is TRASH!! If I were a canine, I wouldn’t give it my consideration Either! It looks large online but when you receive it, it is a Small RAG! THIS Attempt at a SNUFFLE MAT IS INSULTING!!! DON’T WASTE YOUR MONEY on this GARBAGE‼️During the time period I had to return it, I was in the Hospital after having a Heart Attack!!I am still trying to Recover & I CANNOT DO MUCH!! Otherwise I would have returned it!!! It’s sitting in a corner in my bedroom. I had to unwrap the CHEAP PLASTIC WRAP COVER so I could even tell WHATit was. As It was diagonally Rolled UP, I had to unwrap & look at it & show it to my Dogs-The DOGS WOULDN’t get near it & now I’m STUCK WITH THIS PIECE OF GARBAGE THAT I CANNOT GET MY MONEY BACK ON‼️Yes, I am upset ! This ugly Thing hasn’t even been TOUCHED by my 3 Dogs & now I’m STUCK WITH SOMETHING USELESS THAT MY DOGS WOULDN’t even get near & I CAN’T GET A REFUND FOR!!! THIS IS THE TYPE OF TRANSACTION THAT I FIND HIGHLY OFFENSIVE ABOUT AMAZON & the Fly By Night companies they represent!!!!!

Nice but…
Color: Blue Green Orange
Nice but not very sturdy and it comes rolled up so it’s difficult to get it to lay down for your dog.

Both my dogs LOVE find the treat game time!
Color: Orange Red Blue, Color: Orange Red Blue
Both my dogs have loved this for years. Both senior dogs - great fun activity for them and they really hunt for all the treats we hide! My little one usually wins and takes over the game board then uses it as a lounger after :-) It’s very interactive with different ways to hide treats and challenge the dogs.
We’ve had it awhile and it has stood up to many uses and washes. Very easy to store and simply roll out when it’s game time. Highly recommend!
