Mathematical development, the author of this text observes, comes about through specific, easily understood problems that require difficult solutions and demand the use of new methods. Richard Courant employs this instructive approach in a text that balances the individuality of mathematical objects with the generality of mathematical methods.Beginning with a discussion of Dirichlet's principle and the boundary-value problem of potential theory, the text proceeds to examinations of conformal mapping on parallel-slit domains and Plateau's problem. Succeeding chapters explore the general problem of Douglas and conformal mapping of multiply connected domains, concluding with a survey of minimal surfaces with free boundaries and unstable minimal surfaces.

Too hard and heavy.
Color: Fowl Play
Very cute idea but my dog was not at all interested. It’s too hard for her to chew on. She didn’t even care enough about it to rip the outside. It’s hard and heavy. I will stick with the non-super chewer bark toys. They don’t last as long, but she loves them.

Tough & fun!
Color: Betty Bigfoot
This is my puppy’s favorite toy. I’ve bought 4 in case he eventually finds a way to destroy the ball because he is a 1 year old super-chewer. That said, this ball is TOUGH! It’s taken severe abuse from our dog & we couldn’t be more satisfied.

Not as tough as they make it seem
Color: Buck Wild, Color: Buck Wild
My dog chewed it up and destroyed it in less than 4 hours. I have a GSP 8 month old. She’s definitely a super chewer but this didn’t last at all. The tail crumbled apart and she ate some of it.

This is a HEAVY Toy
Color: Buck Wild
This toy is HEAVY. Really good quality, but my dog hasn’t shown much interest. If you can find a way to get your dog to play with it, I’m sure it would last for awhile.

Barkbox Betty
Color: Betty Bigfoot
A lot smaller than pictured. Still like it. Durable. Dog likes to carry toy around. Dog is 70 lbs and a heavy chewer and toy has lasted.
