The discussion is designed for advanced undergraduate or beginning graduate study, and presumes of readers only a fair knowledge of matrix algebra and of advanced calculus of functions of several real variables.

This is a text of local differential geometry considered as an application of advanced calculus and linear algebra. The discussion is designed for advanced undergraduate or beginning graduate study, and presumes of readers only a fair knowledge of matrix algebra and of advanced calculus of functions of several real variables.The author, who is a Professor of Mathematics at the Polytechnic Institute of New York, begins with a discussion of plane geometry and then treats the local theory of Lie groups and transformation groups, solid differential geometry, and Riemannian geometry, leading to a general theory of connections.
The author presents a full development of the Erlangen Program in the foundations of geometry as used by Elie Cartan as a basis of modern differential geometry; the book can serve as an introduction to the methods of E. Cartan. The theory is applied to give a complete development of affine differential geometry in two and three dimensions.
Although the text deals only with local problems (except for global problems that can be treated by methods of advanced calculus), the definitions have been formulated so as to be applicable to modern global differential geometry. The algebraic development of tensors is equally accessible to physicists and to pure mathematicians. The wealth of specific resutls and the replacement of most tensor calculations by linear algebra makes the book attractive to users of mathematics in other disciplines.

Nice Platters for family Thanksgiving take out
The family used these to take some Thanksgiving food home. These paper platters are sturdy and hold food without bending or leaking. I like the size because it works well for bigger meals or when I don’t feel like washing dishes. They make serving and cleanup quick and simple.

Perfect for Thanksgiving and Christmas
These platters are sturdy and just the right size if you’re having a Thanksgiving or Christmas dinner and don’t want to deal with a bunch of dishes. My family use them for the first time this year and we were absolutely delighted. The platters are sturdy, high-quality, significantly larger than the 10 inch paper plates and hold a large amount of food which is essential when you’re serving a large meal.

Perfect for every occasion. Absolutely love this brand.
We always buy disposable tableware from Dixie, and these platters are another great product from the brand. The size is perfect for barbecue food, burgers, ribs, sides, everything fits easily. They’re sturdy, don’t bend or leak, and hold up well even with heavier food. We host BBQs often and these make serving and cleanup super easy. Reliable quality and definitely worth buying again.

these are very nice platter/plates
these are not quite as thick as I was hoping for, but they’re really nice. I guess I’m just used to using paper plate holders underneath them but if you use two together, they’ll hold just about anything that you can put on them.
