Finite-Dimensional Vector Spaces: Second EditionA fine example of a great mathematician's intellect and mathematical style, this classic on linear algebra is widely cited in the literature. The treatment is an ideal supplement to many traditional linear algebra texts and is accessible to undergraduates with some background in algebra.

A fine example of a great mathematician's intellect and mathematical style, this classic on linear algebra is widely cited in the literature. The treatment is an ideal supplement to many traditional linear algebra texts and is accessible to undergraduates with some background in algebra."This is a classic but still useful introduction to modern linear algebra. It is primarily about linear transformations ... It's also extremely well-written and logical, with short and elegant proofs. ... The exercises are very good, and are a mixture of proof questions and concrete examples. The book ends with a few applications to analysis ... and a brief summary of what is needed to extend this theory to Hilbert spaces." -- Allen Stenger, MAA Reviews, maa.org, May, 2016.
"The theory is systematically developed by the axiomatic method that has, since von Neumann, dominated the general approach to linear functional analysis and that achieves here a high degree of lucidity and clarity. The presentation is never awkward or dry, as it sometimes is in other 'modern' textbooks; it is as unconventional as one has come to expect from the author. The book contains about 350 well-placed and instructive problems, which cover a considerable part of the subject. All in all this is an excellent work, of equally high value for both student and teacher." -- Zentralblatt f r Mathematik.

Great turned to not so great
My Doberman (80 pounds in 7 months) puppy absolutely loved this ball. He loves anything noise making so this ball was perfect. Unfortunately, about 2 hours of nonstop play the cover was falling apart. There was no saving in. My pup is rough on toys and this one couldn’t handle it. I let him play without the cover for a little bit but the plastic is VERY hard. I’m not sure what type of plastic it is, but it’s very hard, no your average plastic. It was clunking around and banging into everything possible.
I would love to give it more stars as it might have been perfect for other dogs, or maybe I just got a dud. But having to take the ball away from him was almost heart breaking. Those sad puppy dog ever and him looking everywhere for it. Barking nonstop because, well he want his ball….and being a puppy he is still learning. Had the cover held up for even 24 hours it would have been great. So I have a sad puppy and a lighter pocketbook. It was fun while it lasted.

Lasted less than a week.
Size: Small Size
This ball was delivered on March 7. It was fun while it lasted, but Today, less than one week later, the squeaker which was the unique fun part of this ball, is dead. The ball is still intact, the soft cover still on it, so our corgi never got to the squeaker - it just stopped making sound. Given the point of this ball is to engage a dog to chase after like it was squealing prey, the death of the squeaker is very disappointing.

Glow in the dark dog ball
If u shine a bright light on these balls they glow for 15 min. My dog has a double coat and I live in fl so I play outside at night and this glow ball fits the bill. Lots of fun. The ball is made well and so far has survived the jaws of my king shepherd. Im happy with my purchase and have also purchased them for family and friends

Glowing Orbs can be fun.
My dog loves these balls. He can’t break them, which is hilarious. The fact that they glow and double as a cognitive toy when you hide treats inside is a huge bonus.
My dog is literally darker than the night. We leave the ball near a lamp for 10–15 minutes, then take it outside and throw it. Watching a pitch-black blur sprint at full speed and suddenly seeing a glowing orb bouncing through the night is unreal.
Great toy. Highly recommend.

The ideal fetch ball
Our dog is obsessed with these. They bounce well, they’re squishy enough to meet his chewing needs but strong enough to not get destroyed. We do replace them every 8-10 months because after 2-3 20 min fetch sessions almost everyday they do rip. They have a nice weight to them so they’re easy to hurl 20-30 yards.
