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.

Mis lentes son muy cómodos, y me gustan como lucen, vienen sin medidas yo los adecué con mi Optometrista.
Se aflojan con el tiempo, pero compré una pinza que ajusta los tornillos…realmente lucen como nuevos.

Hotel quality, budget friendly
Size: King, Style: Light
I’ve only used this for several nights. Overall I’m pretty happy with it, especially for the price. It is soft to the touch and has a nice, smooth feel. It’s lightweight but still provides enough warmth for mild to cool nights. I don’t like feeling weighed down when I sleep, so the light fill is actually a big plus for me. If you’re someone who sleeps hot, this is a solid choice. The corner tabs are super helpful. I paired it with a duvet cover and haven’t had issues with shifting or bunching. It also fits my bed well, though I could see it being a bit short on the sides if you have a very thick mattress. This is a great budget-friendly option and seems like it will be easy to maintain.

A Great Comforter for Everyday Use
Size: Full/Queen, Style: All-Season
I absolutely love this comforter! I love the fact it’s machine washable, and it held up really well after the first wash. It fluffed back up nicely, stayed soft, and didn’t lose its shape. It’s not too heavy but still cozy enough to keep you comfortable. For the price, the quality exceeded my expectations, and I am very happy with this purchase. I highly recommend 😊
