Rings of Continuous FunctionsDesigned as a text as well as a treatise for active mathematicians, this volume begins with an unusual notice: "The book is addressed to those who know the meaning of each word in the title." As such, it constituted the first systematic account of the theory of rings of continuous functions, and it has retained its secure position as the basic graduate level book in this area.

Designed as a text as well as a treatise for active mathematicians, this volume begins with an unusual notice: "The book is addressed to those who know the meaning of each word in the title." As such, it constituted the first systematic account of the theory of rings of continuous functions, and it has retained its secure position as the basic graduate-level book in this area.The authors focus on characterizing the maximal ideals and classifying their residue class fields. Problems concerning extending continuous functions from a subspace to the entire space play a fundamental role in the study, and these problems are discussed in extensive detail. A thorough treatment of the Stone-Čech compactification is supplemented with a number of related topics: the Ulam measure problem, the theory of uniform spaces, and a small but significant portion of dimension theory. Hundreds of problems of varying difficulty appear throughout the text, providing additional details, describing counterexamples, and outlining new topics.

Dermatologist recommended
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
I did a light study on these products and this one is recommended by dermatologist with lots of good reason. There’s one dermatologist on you tube that does the most extensive and short, to the point at the same time, explanation of the different products on the market and what you want in a sunscreen. It’s worth looking it up if you used a lot of this product. She wasn’t selling anything but suggested this as one that’s the safest to use you should look that one up if it’s a concern. It’s the best and most simplified piece that I’ve seen on the subject. I recommend this one because that doctor recommended it. I still tan with it but I don’t burn. My pasty white skin likes to burn lol. It stays on with water reasonably well. I like the small package. It lasts pretty good too. I try to travel light and things like this really help. With a light load towel and a few things compact I can carry everything in a very small gym bag. This compact packing is awesome. The speedstick type applicator. The whole thing isn’t just perfect and a great product overall

Silky Smooth
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
Silky smooth texture, goes on easily and works well. Feels a little thick and greasy but not as much as other brands.

Great Even With Excema
Size: 0.47 Ounce (Pack of 1)
This product is amazing. I have fairly bad eczema and am a 59-year-old woman so I've had it my whole life. My lips have had bad eczema since they were sunburned 4 years ago. I had to let them heal before I could use any products but since they have healed, I have been using this product on my lips for sun protection during golf and running outside in Florida. It doesn't bother my eczema at all and in fact I think helps my lips stay moist and even helps heal them when a spot starts to occur. I have about six of them spread out in purses and cars and different spots in the house and of course my golf bag. I would highly recommend this product. It does make my lips turn white but I really could care less because of the level of protection that it provides. It's worth it and it wipes off easily with a tissue. There are many, many products that Ive tried that irritate my lips and cause a rash and this is one of the few that does not.

Yes !
Size: 0.47 Ounce (Pack of 1)
I order these every summer. My youngest is sensitive to sunscreens but this had always worked for him. The stick is handy when it comes time to re-apply and can stick in my purse for a quick trip to the park.
