"The book is extremely pleasant to read, with masterfully crafted exercises and examples that create a beautiful and unique thread of presentation leading the reader safely into the wonderfully rich, expressive, and powerful theory of categories." -- The Math AssociationCategory theory has provided the foundations for many of the twentieth century's greatest advances in pure mathematics. This concise, original text for a one-semester course on the subject is derived from courses that author Emily Riehl taught at Harvard and Johns Hopkins Universities. The treatment introduces the essential concepts of category theory: categories, functors, natural transformations, the Yoneda lemma, limits and colimits, adjunctions, monads, and other topics.
Suitable for advanced undergraduates and graduate students in mathematics, the text provides tools for understanding and attacking difficult problems in algebra, number theory, algebraic geometry, and algebraic topology. Drawing upon a broad range of mathematical examples from the categorical perspective, the author illustrates how the concepts and constructions of category theory arise from and illuminate more basic mathematical ideas. Prerequisites are limited to familiarity with some basic set theory and logic.

Good quality
Color: Pink, Size: 50"Wx60"L
My great granddaughter asked for this throw so I purchased it for her. The throw is so soft and looks exactly like the picture. The quality is good and the price was right. It’s light weight so she can roll it up and throw in her backpack to take to friends houses. I received the throw on time and I would recommend this product and seller.

It sheds
Color: Pink, Size: 50"Wx60"L
When I bought the blanket with the assumption that it would be pink leopard on both sides. Unfortunately, when I retrieved, my package it was white on the inside and pink leopard on the outside. It was nice until it started to shed so I gave it to my sister. I did not like the size I should've gotten something way bigger. It will keep you warm though. Especially during your period. It wasn't all the way soft because one side was odd the other is what you actually offer so that part I didn't like very much. Overall it does get the warming job done.

Different than I expected
Color: Pink, Size: 50"Wx60"L
Thin fabric for a throw blanket. Doesn’t look anything like the photo of the product. Pattern is somewhat off and different looking than expected.

Pdvbiee - Hot Pink Cheetah Flannel Blanket
Color: Pink, Size: 50"Wx60"L, Color: Pink, Size: 50"Wx60"L
UPDATE: 4 months later ... I sleep with this blanket every night. It is soft, warm and comfortable. It has held up well through multiple wash cycles with no fading, unravelling seams or matting. Still wish it was printed on both sides (really the only reason it's not 5 stars especially since they don't show this aspect in the ad listing), but overall I'm glad I have this blanket!
ORIGINAL:
I'm a sucker for this type of pattern (hot pink leopard), so I knew I had to have this throw blanket. When I opened the package, I felt a bit let down because the back of the blanket is solid white, which I hadn't noticed in the ad until after I placed my order. It had a faint factory smell, so I thew it in the wash. I was slightly concerned the hot pink color might bleed, but that was not a problem. It washed and dried easily, just as I expected. It definitely feels and looks cozier and fluffier after being laundered. Although, you can more easily tell that the hot pink cheetah pattern is just printed on the blanket, particularly when folding over the darker areas. It still looks cute and will keep me warm, but it may not become my favorite blanket as I initially thought it might be. I also think the price could be a bit lower considering the pattern is just printed on white fabric. There were also already a few loose threads at the ends.
