Many applied mathematical disciplines, such as dynamical systems and optimization theory as well as classical mathematical disciplines like differential geometry and the theory of Lie groups, have a common foundation in general topology and multivariate calculus in normed vector spaces. In this book, students from both pure and applied subjects are offered an opportunity to work seriously with fundamental notions from mathematical analysis that are important not only from a mathematical point of view but also occur frequently in the theoretical parts of, for example, the engineering sciences. The book provides complete proofs of the basic results from topology and differentiability of mappings in normed vector spaces. It is a useful resource for students and researchers in mathematics and the many sciences that depend on fundamental techniques from mathematical analysis.

In this second edition, the notions of compactness and sequentially compactness are developed with independent proofs for the main results. Thereby the material on compactness is apt for direct applications also in functional analysis, where the notion of sequentially compactness prevails. This edition also covers a new section on partial derivatives, and new material has been incorporated to make a more complete account of higher order derivatives in Banach spaces, including full proofs for symmetry of higher order derivatives and Taylor's formula. The exercise material has been reorganized from a collection of problem sets at the end of the book to a section at the end of each chapter with further results. Readers will find numerous new exercises at different levels of difficulty for practice.

Cute toy that definitely entertains the pups.
These are adorable toys. They make a bit more noise than I expected as they have the crackly ‘stuff’ in the legs. My mastiff made it a whole day without destroying it. This is the first toy that’s survived him for more than 10 minutes, so that’s an endorsement even if it sounds bad. They are a great price for the size. If I were to say I have a wish for them, it’s that the material that makes up their belly was more durable.

Durability Not So Good
The size is great and having squeakers in all tentacles is super for the puppy but had to sew a seam withing one week of having it. Hoping the rest stays together.

Long lasting and fun
This toy has lasted longer than other octopus toys I've bought in the past. Even if a leg or two is ripped off, it still holds on.

Awesome product, but NOT sturdy
My dog LOVED this product, but unfortunately the head came off in less than a week.

Glad this toy is back
Large soft dog toy. I have been trying to buy this item for years. It apparently was discontinued, but it finally has been replaced with an even better, more durable product. I have two large chocolate labs and they have yet to gut it. It is reasonable durable, but I suppose a determined dog could eventually rip into it. I will definitely again. Large grunting noise maker in the body, and small squeakers in the arms.
