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.

Beautiful, Solid Real Wood Wrist Rest
Color: Walnut Wood, Size: Large
This wooden wrist rest feels premium and the finish is super smooth — it’s noticeably nicer than foam or gel pads. Real wood looks great on my desk and still feels comfortable during long typing sessions. Definitely worth it if you want something stylish and functional.

True-to-photos color, solid build, and great for organizing
Color: 2Pcs Green
Durability: This tray feels well-made and sturdy. I replaced a fragile tray that shattered when it fell, and this one feels like it would hold up far better to normal day-to-day handling. I am not going to stress-test it, but it feels substantial and nicely finished.
Use and ease of use: It does exactly what a tray should do. It is easy to carry, stable when set down, and the woven leather surface feels secure and helps keep items from sliding around.
Color: The green woven leather matches the website photos. No surprises, no weird undertones. It looks clean and high quality in person.
Organization: This is where it really shines for me. It is a great fit for corralling items on a table, counter, or dresser and instantly makes things look more intentional. It is not stackable, but it is not advertised as stackable either, so that is fine.
Size and accuracy: The dimensions match the schematics online, which I appreciated. It fits the space I bought it for exactly as expected.
Overall, it looks high-end, feels durable, and is a simple upgrade if you want a tray that helps keep a space organized without feeling flimsy.

Nice tray!
Color: Black
This tray has helped me organize my desk better. I use it for my phone stand and charger, as well as a place to hold and charge my vapors. It has a nice rubber mat inside so nothing gets scratched on the wood. It is well put together and seems very sturdy. I think it will last a long time! It works for anywhere in the house.

Classic gents’ tray
Color: Black
This tray is large enough to hold the items a guy normally carries around in his pockets (e.g., wallet, eyeglasses, cellphone, money, keys, lip balm). The tray is lowkey attractive and keeps a dresser from looking cluttered. The tray bottom is thin yet sturdy. Good price and worth the buy.
